I enjoyed the cute art style, but the technical issues made me not get further then the second dialogue part. The boxes rounded corners of the platforms make the character slip off, and there is no leniency for when you can and can't jump. I suggestfor concrete tips.
The UI looks fine, but it would have been better if the tutorial message wasn't put away in the corner. Also, the walls are sticky, as in you fall slower down if you hold walk while fallign alongside the walls/platforms. And there also seems to be a bug with jumping while colliding with a wall, giving you a massive jump boost.
