Nice game! I like the visual cues in each area to hint at what to do, the jumping having momentum was quite cool as it allowed your to take on the spike level in different ways you could take daring jumps to skip a couple of spikes at a time, the hitbox on the spikes seems a little large and it would be nice if you could smoothly walk over them when they are down, as it seems you to have to jump to directly get over them. Great work though
