Very cool entry! I love the tight game loop you've made, and how it loops with the Ohh my head part too :)
It mostly feels pretty good also; not sure if this is on purpose but forward and back moves a lot faster than left and right. It would be nice if left and right moved you precisely as fast as forward and back do.
Also, since you are mostly in the same environment the whole time it would be nice if there was some more texture variation. I know it was a tight time lime for this jam though.
Music was appropriately moody too. Overall lots of fun!
