I saw the little Red Bird sprite and knew I hade to try this one, and Im glad I did. Everything looks really pleasant, charming and cohesive (even if there is alot of bird death going on lol). The movement was really unique, getting the hang of it was almost its own puzzle before the dangerous winding caves. I do think it would help if you are introduced to the flight in a level with no danger, that still required a little bit of mastering the physics to complete, just a sort of playground space after the tutorial explanation. Some of those levels are really punishing, even if they didnt have spikes everywhere. Possibly a slow mo power might be good for making those precise turns, especially in the last 2 levels. I did manage to beat it though, and got all but 1 of the eggs, I have no clue how to get that last one and still be able to get high enough to get back on the tree. It was a super nice touch how the menu changes after you finish the game too! There were honestly alot of nice details that make this feel complete, like the visual indications for the traveling at lethal speeds, automatic saving, and level select. I'd love to hear a few different sound effects for the bird and maybe a unique one for the egg pickup but those are really minor points. Amazing game!
EDIT: I didnt realize there were more levels, I stopped after saving the first blue bird, I'll have to play some more haha.
