The game was pretty good!
The sprites and some of the animations were pretty cool.
Movement in the game felt a little sluggish and even a bit floaty at times.
The power ups/allies felt really useless to be honest, the player could already double jump from the start (most likely a bug?), so the double jump power up didn't change anything, and I didn't really noticed what the rocket boots did, but I was still able to beat the level anyways.
Anyways, cool game and well done!
