Wow great, this had the whole story to play - and i played it to end! Very cool, the ending was a surprise. Everything works together, i guess: Icy friend controlled the world and created spiky creatures guard it. There were no aggressive hostility and the there was something to really do. Some real levels into this too!
The camera angle was a problem, it should be rotating or from a longer distance to the player character. Also the jumping height could be more higher, so the player would have some time to decide where to try land. Some different enemies variations would be great too. I really like how your character can "charge" and move faster and be more effective. Idea in this is like to combine Super Mario + Sonic, but it's fun to see how far you get with this for a Jam game.
