Malek, I am happy to have played your game and have seen how great the sound and graphical design are.
There are some few problems for me though, the player’s max speed is a little too fast.
There are also some blind jumps to transitions like the upper section where you learn how to walljump, I think that too many people would just not have the proper reaction time to the spikes…
Anyways, nice game all in all!
