Hi, I am happy you liked our game. We didn't have enough time to make good balance, so everything was like an educated guess.
About colour, lol, I completely agree with you. We actually were arguing with my teammate about this, with him saying that red is good and green is bad. He made the graphics and i completely forgot about this, so that's what we've got.
Game stopping to respond isn't inteded and is an unofortunate bug, sadly we have figured it out only after jam had been finished.
