Great game! I really like the aesthetics and the level is huge, congrats!
The layout kind of remind me to some Sonic levels (because of the multiple levels and leaps of faith).
Some feedback:
1) The hook cooldown is too high and it needs some visual indication.
2) With a game as long as this one, you need some kind of checkpoint. I died really close to the end (I think haha) and it took me to the very start, which is very frustrating.
3) It could be great to have some sense of progression. Maybe saying that the launch should be done at dawn and see how the Sun starts to appear while you reach certain points.
