I really like the hand drawn black and white 2D artstyle in a 3D world, very cool aesthetic! I only wish the platforming mechanics were on the same level. Everyone else in the comments here has made the excellent points that some additional camera movement and a drop-shadow below the player would help a lot. Also the sound effect for the jet-pack is a bit delayed, for future reference it's really easy to cut/modify an audio clip with a program like Audacity. Very cool submission overall though :)
