I really loved the progression! I see the similarities between our two games indeed.^^ The mood at the end was incredible, the descent afterward reminded me A Short Hike. It was a really sweet journey! Nice work too on the colors and cloud rendering, as well as the great sound design.
The game was quite hard at first. I struggled to climb the first level, then spent a lot of time falling in the second time. Then the third seemed like a wall, I just couldn't find a good way to get just an inch up. But then it clicked: contrary to the tips, I went against the wind (to the right), and I realized how much powerful lateral movements could be! The game then became really fun. Instead of trying slowly to catch drops, my strategy was to pick a lateral direction (left or right), gain as much speed I can, to the swoosh with X to get a lot of height, and keep going like that by catching as much drop as possible, using space to boost myself slightly upward (but never completely vertical). It really felt like flying, the game becomes a fast paced platformer, and is never too punishing because by flying in one direction you always come across a drop of water (even in level 2!). I wish the game would have taught me earlier to play like that. I don't know how, maybe a tutorial, or animals that show the example, or maybe even text. It could incentivise more lateral movement, to avoid the frustration of trying to go straight up, and then falling. Because once you understand the correct way to play, it becomes really fun!
