I liked this game a lot.
The music is very adequate to the theme. The character is very funny and the SFX are hilarious.
Also the concept of transforming the whole scene from 3D into 2D is interesting (although I would prefer using the 3D View always...).
The 3D Environment is very well set, and it was fun to explore it.
Ps: One thing I would add to the game, (to make it even more challenging) would be some enemies (and the ability to fire / shoot a weapon to defend yourself against them).
Congratulations, it is a very nice game, especially for a one man team.
