I understand that it's short, but I think it's too short. Add more levels and build on what you have. The movement feels great.

its nice, the controls feel good, and collisions feel right.

the only problem that it isnt even a game, it feels more like a unfinished prototype.

other than that. its an "ok" game. would have been better if there were more levels & mechanics

You've got an alright idea here, even if its execution was a bit barebones.
You can easily expand this into a much more fleshed out title.
