I really enjoyed the idea of this game and appreciate how different it is! Though, while my friend and I were impressed by the first couple of minutes, the game got extremely repetitive very quickly. If you were to expand the game after the jam and make the progression much longer I believe that would help!
The multiplayer features did also feel very tacked on. It felt like this was a singleplayer game, with multiplayer desperately added on at the last second.
Overall, nice game!
