Just finished this game and it has been a blast.
The switch for the secret stash is a bit hard to find as you have to jump and press E as you can't see it. (I was thinking it was on the ground.) xD
The controls are a bit that way as I would of had S for jump as that will allow the player to move, jump and attack at the same time.
I would have W for switching forms.
Other than that the game is really fun to play.
Gonna move onto Slash Cucumber xxx as it's the last one to do.
