Pretty cool game! I like how you incorporated the cheat code as a core mechanic (over something to enter in a console)! The movement is ever so slightly (not by a lot) too rigid. But otherwise, I had a good time playing it and think your sprites are really cute ;)
I also agree with what Emma said, it reminds me a lot like VVVVVV (a great game if you haven't tried it!)
Nice Job and Game On!
