The parallax in the background was really cool, I felt like at least in PC the game was too punishing since the beginning, so maybe you can start it easier and build up the difficulty. Also changing the color scheme on other hot balloons can make it easier to recognize them as obstacles, mi first playthroughs It wasn't clear if they were enemies or collectibles TBH, besides that really enjoyed your game, Great Job
