I really like the way your game looks, it's very brightly coloured and stylised. The game also functions really well and the 3D models look really nice.
I would suggest adding a death/respawn to your game next so that there's an element of challenge involved, and add some collectables of some sort to add a goal to the game.
I also noticed that when moving really fast from either left or right into an obstacle can cause the character to get stuck and rapidly jitter up and down. I'm not sure if you've noticed that, but it's a detail that should probably be looked into. Aside from that, it's a great game, I really like the visual style you went with.
