What a great idea! I gave full marks in creativity and technical. I love the 3d pixel style and simplicity of controls.
It was a bit too easy at the beginning. I didn't have to start ducking and dodging until about 9m, but that's when it started to get really fun. I know dialing in difficulty/timing tends to get put off, but all it needs is some polish in that area.
I actually played it with the sound off the first time and enjoyed it more than playing with the sound on. This is just opinion, but I think just music and no SFX would have been better than no music and repetitive SFX.
Overall, a fabulous submission - good job! :)
