It's a fun idea, but I feel like it could use some polish and bug fixing. I saw some flowers and rocks flying in the air. Some colliders are inconsistent, like most objects are pass though, but then there are some which are not - and then a bunch of enemies gets stuck on them, so you have to scout the field to find them to finish the game. The introduction screen could use a game pause, so that the player has a chance to read the message. But good job overall!
