The aesthetic is clearly what brouht a bunch of us to your page; and it is really great. Wholly unique for what I know of jam games, so really amazing job in cultivating that!
To me the gameplay felt a little undirected; some audio or a little more on-screen hints (as in through colour or level design) would have really helped me progress more naturally. Sadly after clearing the first obstacle I felt totally lost, taking me a few goes to even realist the coloured clouds were seperate from the background.
Seeing as to how unique the art is, it could have been cool to really find a unique core to the gameplay to compliment the strengths of that style.
