Volume - You need volume bars from 0 to 100
                     one for music and one for sound. i hate playing without sound

Lack of attrition - it looks like it slides the cube some times (not my opinion - my friend opinion)
in the tutorials put checkpoints (not my opinion - my friend opinion) They where 2 hard for somebody new but it can be easy to fix with checkpoints
Reduce the gameplay box - Sometimes you fall and when you do fall it takes a long long long time to get to the respawn , that or make a button to restart the mission since there is no checkpoints it would restart completely

I hear you!

Volume - working on it

Lack of attrittion - This is not an easy game. "Dark Souls of platformers" they said.

Check Points? Pfff

Yes i am aware of the issue with the respawn time taking too long, will be fixed in latter releases.

Thank you so much for playing and sharing!
