Okay, this is awesome but man do you gotta smash that space bar haha! The overall vibe is great, very Christmassy and I liked the little goofiness in the music. My only gripe would be to make one press of space jump higher, maybe closer to Flappy Bird kind of deal. Cuz falling would allow you to dodge the birds faster than trying to maneuver over them right? Helps make the coins lower on the screen more worthy to risk for. Santa could also be further to the left too, if that makes it too easy then you can still increase the speed, think that'd make it feel more intense as well.
Overall beri vute. :3
