Oh my god the penguin is so cute. I love the ice skating theme, very creative, and I also really liked the music/rhythm based movement, I think that's a very smart idea. Also nice with checkpoints, but sometimes there were almost too many checkpoints, because I had to go back on a lot of platforms to gain speed to clear a jump. I think the purple block mechanic was cool too, but a little hard since I felt like sometimes I flew high, and sometimes I barely lifted at all.
I also sadly couldnt figure out how to do the final high jump tho :(( But other than that it was a great game and I would have played more penguin platformin levels if I could!
