Good shoot-em-up game. The cannon totally broke the game though, I ended up just mowing down everything with it. I easily made all the way up to level 20+ by the time I fought with the bosses, and I just gunned them all down. The swords just ended up as decoration on my character's waist :) (Speaking of which, seeing the items you've picked up on your character was really cool)
The camera gave me some hard time, especially at the lower left corner of the room. I tried climbing to the desk over there, fell and got stuck on my way down for a bit; where a weak enemy was able to hurt me for a bit (and it was the only time they were able to do so. Har har har). I'd love to have an ability to turn the camera around, it would've helped to actually navigate the room.
I also saw a few places where the collision was a bit odd (i.e. the area under the bed seems accessible normally, from its left side, relative to our camera) but you actually need to crouch or roll to get in).
The presentation was nice, and the way toy enemies turn into toy giblets was quite satisfying. The music though... was *very* repetitive :D
Overall, a good game! I'd love to see it get improved upon. Cheers!
