Thank you for the feedback! I will definitely consider the mechanic. If you wouldn't mind, could you let me know what bugs you found so I can fix them?
Ah, of course. After you jump into a wall (such as the floating platform in level 2), and you try to jump the same direction again, you just jump up instead of going in that direction (when you jump the other way, it fixes itself again). And I once jumped into a wall and stayed halfway up, also being able to jump from there. It's also possible to wall-jump :p
