Amazing work for your first game!! I really like the vibe of the game, reminds me of classic casual games youd find on the app store back in 2010-2015. The use of different biomes adds a nice touch of progress, and I like that you made multiple levels. My only request would be to add the ability to look up and down with the mouse to better guide the ball and potentially also a controls screen/popup? A great next step would be to work on adding sound effects for jumping and moving and maybe even some new elements to introduce in later levels. Keep up the great work!
