I liked it
The game play is nice, it was really fun. I really loved the idea of the dog swallowing stuff and shooting em out when he barks. The art is nice, very creative.
I read your comments and I gotta say, you've achieved what you wanted. I really felt like a 5-year old.
There's a little bug though that really annoyed me. I got shot down while going through the transition when the screen would tiltand had to redo the boss fight, but the screen had tilted and it took us away from the city into the sky.
The bug wasn't enough to take the fun away though. It's good. It's original. It's fun. 9/10 (because of the bug). Good job.
