For a game jam, a game without a win / lose condition really makes it stand out (atleast I couldnt find them). Feels like a really cool version of cookie clicker, with additions to fit the theme.
Visually it is incredible, and I really have to give credit for making a tileable pentagon game, because that seemed impossible when the limited shapes were released. I do think that the game accidentally allows for other shapes to form than allowed, though it does not bother me as the game itself, and the placingsystem, is stunning.
Personally, I do think the game would have worked a little bit better if there was some sort of win / lose condition, as a sandboxing game is quite hard to properly experience with the limited time people will rate the game.
You have got to be proud of this, because it looks really really good.
