This is some good stuff. Very well-made visuals and fun gameplay. And the WebGL version works very well with no issues.
I think some people are getting stuck on that level where you have to jump down to get the last coat because you have to go down from the left side of the starting platform. If you go down from the right side of the starting platform you get teleported back, which makes people think there is nothing below that part, so they don't try from the other side.
A polished game and nicely done mechanics overall. Good job.
