This was a fun game--very charming little demo and unique protagonist. Bonus points for making the dog a green outline in your menu screen.
I thought the music was creative but in general it kinda felt more rock-and-roll and fast-paced--I think I'd have expected a more action-oriented area or even a boss.
The jump feels a little "fast" going up and down; I would probably recommend a slightly more "floaty" jump.
But once again very charming; following to see what you do next with this or otherwise!
