Dude, I returned the game from Steam because I didn't understand it. But I noticed something. When I went to the file location of the game, I saw that it was still playable (but it cannot be opened from Steam.) I registered here to write about this situation :)
That's a little odd. The game has no DRM so perhaps that has something to do with it but I would've assumed Steam would uninstall the game first. Thanks for letting me know though ;)
If you have time, could you let me know what parts I did a bad job of explaining/teaching? Is the tutorial not good enough?
