Hahaha, cool game! Fun art, but with style. In full-screen mode on the second level, not all the stones are visible, which I did not immediately understand, perhaps this was intended, but in any case, I played with a smile!
Thanks for playing! Making people play with the smile was the main point :D. It may be a browser bug (I have tried other games on the jam in different browsers and there are visual issues). You can skip to any level by pressing keys 1 to 5 though :)
