Made it to the end, pretty good platformer !
I liked the difficulty curve, the game could improve with some polish like a death animation, and for getting less frustration it's possible to reduce the hitboxes of the obstacles (even if they're shorter than the sprite of the threat), for the last course I got hit a lot by the floating spikes even though my body wasn't on them
Even if the gifts were direcly on the road of each tracks, It was pleasing to gathering them to finish the levels !
Nice job !
