First of all it's got a great presentation, from the artstyle to the UI etc - everything from the sun and waves drawing to the background. I struggled quite a lot with the core game - I noticed on the game page you talked about the input sometimes being unresponsive, I had this issue, but I think even when it was working, it just took too long to start moving and was very slow. This may be intentional but it felt like some obstacles I just couldn't avoid. Conceptually, with flying acting different as you spend time closer to heat/water is great.
Aside from that, the transitions were great, and a lot of the tertiary stuff felt really polished - I hope you continue to work on this, great job!
