Summary of this game: Chrrrrrrrrr Chrrrrrrrrr Chrrrrrrrrr :-D
Pretty impressive game considering that it’s your own engine and that it’s procedurally generated. The maze is really big and it’s a bit tedious to check all the rooms, but it helps that the crystals glow through walls.
For future games, I think you need to disable mouse smoothing, because it makes the game feel unresponsive. I also thought that ESC would pause the game, but it quit instead, it was a bit annoying to lose progress.
I like the graphics and ambience, it really feels like you are on a foreign planet. Though I think it would be more fitting to name it Jupiter, since it has no surface and is covered in storms, just like in the game. :-P
