I have played and rated your game, the concept is interesting and I liked the cute pixel graphics. I think you should add an "end condition" (now it feels like the game is endless, but maybe I did not wait long). Also, maybe you should change the controls - if you already use arrows, maybe use a key other than mouse click for switching (Shift for example). And finally, an English manual would be good.
But it's a good try!
I'd like you to play and rate my game too! https://itch.io/jam/mini-jam-177-papercraft/rate/3297612
