A very nice platformer. Great work visually - especially the main character is very well designed. The environment feels very arcade-y which seems to be the vibe you were going for. The checkpoints helped a lot, though in either 3rd or 4th level (I kinda lost count) - the one when you go left, drop, then to the right - might want to ease back the difficulty there, cause I dead A LOT there.
-I don't think I got all the golden collectibles (had a score of 590), but they felt great to collect - good job there.
-I died 25 times, though deaths from spikes didn't seem to increase the counter. Might want to look into that.
-The main music loop was nice, but I had a feeling some background layers were really noisy - as in - there was some random noisiness in some parts of the music loop. Just felt a bit weird.
