Gameplay-wise - this looks fun. Auto-running with skilled jump execution is always a good time. There does appear to be some collision issues, especially when you jump under a ledge. Did notice a bit of procedural generation (or randomised map chunks) which is cool to see.
Art-wise - some tiles appear to be added as if they were templates. For example, dirt tiles appearing above grass. It can give a slight rushed look - as if this was made using pre-existing assets.
