Thanks. You might be the only one who's said this game easy (as a dev I feel it's easy too, but then again, I know from the start how everything works...)
For now there actually is only one such part where you fall and have to climb back again (the rotating platforms).
On fixed version there's another one like that (first water platform, if you fail you'll have to climb fast back up and try again, or drown) but I'll be sure to add more since I want to develop this further and see where it goes. Basicly, I want to use such means to teach mechanics and after player is familiar with it, I want to test player if it truly is mastered.
I also hate floaty jumps in games.
As for art. Szadi art. and Luiz Melo (Unity asset store) are both awesome pixel artists and I'll definately use more of their assets in the future.
