Cute and short game, you've got some interesting speed boosting and timing mechanics here! I recommend expanding upon that and experimenting, it will make your game stand out if done well. I will say the hit recovery takes a bit too long, at least for how many obstacles there are on the tracks. The double jump is helpful, it would be cool to have a dive or dodging mechanic to get around some of the hazards.I enjoyed the music as well, it's jolly and cute
Nice work :)
