I really enjoyed it, the concept is pretty interesting. The only downside is the amount of content and the game time (I realize this is due to the time limit on game jam). I will recommend my fellow teammates to play it too :). I even want to give some suggestions:
-Maximum quantity is OP
-Diversity of enemies
-Big boss coming out of a big mushroom.
-When you destroy everything, you're just stuck there waiting until you realize you need to go back (I realize you can figure it out quickly, but it would still be nice to automatically go back)
-2x speed button, especially before you can get your hands on an army of mushrooms
