Yeah, I really didn't understood what to do, maybe a tutorial inside the game would have been a good idea.
Fair point. Didn't have enough time to do that, it's my own fault for getting involved so late in the jam. That's why I wrote a short description with the goal and controls on the itch.io page, but I guess nobody reads that.
Maybe a little text when you start the game could have been okay, but don't worry, Ialso didn't made a good tutorial for my game XD.
