Once upon a time, a magical sea cucumber with a fantastic hat fell into the world. Oh no, that was the other game.

Okay, let's start over.

200 years ago, a meteorite fell on the world and triggered the gift of magic in some people. Humanity split into three fractions. There was a battle over the meteor, from which the church emerged victorious and from then on imposed several rules on people how to use magic.

Today only the books tell about this long forgotten time. People have long since become accustomed to the control of the Church. Magic is no longer used.

Until young Harold finally finds an old treasure map and sets off on an adventure with his best friend Marsha. However, the mysterious treasure of the Moonlight Lake can not be found without some obstacles and puzzles. But what does it all have to do with the impact of the meteorite? Harold and Marsha eventually come across information that sheds new light on long-ago events.

Much of the background story can be found in the game in the books. To fully understand the story, you should not miss this!


Harold and Marsha

Two friends who grew up together in the peaceful village of Trisca.

Harold is a bit simple-minded and naive.

Marsha comes from a family that received the magical gift when the meteor struck.

But since the church of the traditionalists is in charge, magic was forbidden and only very few people are allowed to practice magic, and only on the instruction of the church.

Einst fiel eine magische Seegurke mit einem fantastischen Hut auf die Welt. Ach nee, das war das andere Spiel.

Okay, nochmal von vorn.

Vor 200 Jahren fiel ein Meteorit auf die Welt und löste in einigen Menschen die Gabe der Magie aus. Die Menschheit spaltete sich in drei Fraktionen. Es kam zum Kampf um den Meteor, aus welchem die Kirche siegreich hervorging und fortan den Menschen etliche Regeln auferlegte, wie die Magie zu benutzen sei.

Heute erzählen nur noch die Bücher von dieser lang vergessenen Zeit. Die Menschen haben sich längst an die Kontrolle der Kirche gewöhnt. Die Magie wird nicht mehr eingesetzt.

Bis der junge Harold schließlich eine alte Schatzkarte findet und sich mit seiner besten Freundin Marsha auf ein Abenteuer begibt. Der geheimnisvolle Schatz vom Mondlichtsee lässt sich jedoch nicht ohne einige Hindernisse und Rätsel finden. Doch was hat das alles mit dem Einschlag des Meteoriten zu tun? Harold und Marsha stoßen schließlich auf Informationen, die auf lang vergangene Ereignisse ein neues Licht werfen.

Vieles von der Hintergrundgeschichte kann im Spiel in den Büchern gefunden werden. Um die Story komplett zu verstehen, sollte man sich das nicht entgehen lassen!


Harold und Marsha

Zwei Freunde, die zusammen in dem friedlichen Dorf Trisca aufgewachsen sind.

Harold ist etwas einfältig und naiv.

Marsha stammt aus einer Familie, die beim Einschlag des Meteors die magische Gabe erhielt.

Da aber die Kirche der Traditionellen das Sagen hat, wurde die Magie verboten und nur noch ganz wenige Menschen dürfen Magie ausüben, und das auch nur auf Anweisung der Kirche.

- jeder Kampf ist fix eventet, es gibt keine Zufallskämpfe

- ein paar Rätsel wollen gelöst werden

- ein Auftragsbuch (Questlog)

- 25 Errungenschaften

- ein paar Puzzle und Minispiele

- 47 Bücher, die eingesammelt werden können mit Hintergrundgeschichte

- ein paar lustige Anspielungen und auch sonst an einigen Ecken Humor

- zwei verschiedene Enden

- fünf verschiedene Waffen: Suche dir die Waffe aus, die am besten zu deinem Spielstil passt

- das ein oder andere Secret

- drei verschiedene Schwierigkeitsgrade

Ha! Seacucumber reference in description to your sea cucumber game! Funny!

Nice long description! And ooh, using the starter names, Harold and Marsha! Really connects with me, who has played many Harold games!


Hello, thank you for the kind words :)

Glad you like it. Everyone likes sea cucumbers :D

This game was a jam submission. One rule was that we had to use the default hero, which is Harold in MV. So I had no choice with the name, but tried to set up an interesting story. I hope you will like the story also :)

Good news is I got the save working in the download version, bad news is I'm stuck using the log to get it across the lake. The one spot I can jump puts me in a small spot I can't get out of. There are trees on both side and I can't climb the cliff or even go back across the log. There's probably something I'm missing.


Glad it works in the downloaded version.

No, you don't miss anything, but try to click on the trees at the left side :)

(1 edit)

That's what I was missing! There's not much to make that tree look different than the others. Maybe if the event activated as soon as the player bumped into instead of requiring an "enter"?

Thank you :)


This is absolutely working as intended. After all, it's an rpg, and in most rpgs, you need to look for yourself. Since you do not have much possibilities (you can't go back), the path forward is not too hard to find, I think. And there will be harder puzzles to solve than that :) 

Have fun playing :)

Okay. Not sure how I missed interacting with that one tree. I made it into the cave yesterday and have gotten to the lab and fought (spoiler). This has been a really fun game so far :)


Glad you like it, this means a lot to me ♥

Hi. I tried to reload the game in the web version, but the game will not remember my save files :(


Oh, that's sad :( Might be a problem of your cache or something because it's working for me. I'll just copy the info from the game's site:

Note: If you have issues while playing the browser version, please be aware this game can be played in browser, but it isn't optimized for that. So if you encounter any problems, please consider downloading it. If the error still consists in the downloaded version - please tell me! I will fix it as soon as possible!

Did you perchance just add an autosave feature? The RPG Maker game Cube Dude's Farm had a similar issue with the game not saving that was tied to the autosave feature. The post no longer exists since they changed the comment section to a community forum, though I was able to find it in the recent posts on the author's profile page:

"Issue is related to autosave feature, I have re-scripted it and now it is working. Game will be autosaved on the actual slot"

No idea if this helps you at all. I will probably download the game like you suggested to be safe. Anyway, I do want to say that I am really enjoying the game and was having fun reading all the background lore and look forward to getting further into the story. Hopefully when I download, it will keep my save this time :)


Thank you for this hint!

Yes this game has an autosave, on two slots that alternate. Is your dissapearing save game that one from the autosave or from a manual save?

Unfortunately, I'm not able to re-script the autosave feature on my own, so I'm afraid we have to deal with this, sorry :(

Love to hear that you enjoy the game despite this issue. Hope it will work in the downloaded version, so you can enjoy the rest too :)

It appears to effect all the saves. To bad it might be stuck like that. Maybe if you took autosave out of the web version?

About to download so I can continue my adventure :)


Good idea, yes of course I could do that.

Right now, it's super busy at work, so I don't have time for an update. So I hope everything will work with the downloaded version so you don't have to wait.


Hello there, do you have english language version?

Yes of course! Thanks for asking.

Just download the game, it has an option for german or english. No different version needed, it's all in one. Have fun playing!

Thanks for answer.

You're welcome!

Don't hesitate to contact me again if you have any questions.

Mt 9, 13 & >Mt 12, 7< könnte implementiert werden;-)!

Ok, ich glaub, ich weiß was du meinst. Die Aussage ist natürlich richtig, passt aber leider hier nicht ins Spiel. Es ist gewollt, dass das schlechte Ende so endet ^^
