I love the idea of the game! The weapons were funny and how they change your playstyle was interesting.
Great job on finishing the game, the soap bar is clearly the best weapon :)
The biggest problems I had with this game was the enemy spawn of those green things which shoot the projectiles in a way where you are guaranteed to get hit by them, and some of the weapons seemed to behave quite inconsistently, so I never knew whether or not it would actually hit the enemy.
