Very nice! I really liked what you did with the visuals, I'm impressed.
The unexpected factor is similar to my game (check it out if possible :)).
The gameplay is pretty smooth, the game just have one bug (which I had in my game too), which is when the player stays in the ledge of a platform, the gravity keeps accumulating, and when you get out of the platform you fall very quickly because of the gravity.
The audio is pretty cool too, the sound effects when you jump, win or lose and the atmospheric sounds fits perfectly with the game.
I just didn't understand the ending. It shows the game's name and then I stay in the level, but the enemies are gone.
Also, the level with the planes that don't have meshes/collisions on both sides are really frustrating.
Overall, really well made, I enjoyed playing it!
