This game is all about the trade off between control and progress. Do you take it slow and steady, but progress slowly? Or do you take a risk and go for speed, so you can have a chance to get further? I really like the mechanics, although they are a bit difficult to get the hang of. Sometimes you can anticipate your demise before it even happens, if you happen to get stuck in a corner you may realize you have no chance of escape before it actually happens. This can feel a bit frustrating, but such is life for a baby bird falling from the sky...
Love the pixel art and the ambient music! Sometimes the level restarts so quickly and you immediately fall into a branch which spawns directly under you. It might be good to have a short grace period in the very beginning of each playthrough.
Nice job on this game and really creative interpretation for "momentum"! You really feel it in the gameplay
