I think a lot of this game's movement does not work ideally. From choices like the wall jump not giving you back your double jump to stuff like spikes not letting you jump off or platforms not letting you fall through, I was not able to traverse the world very easily.
I do quite like the visuals. Each of the sprites for the character and the enemies feel natural but strange in a good way. The background in particular is striking.
I only got to level 3, I would be interested to learn how far it goes.
