Hi bilgekaan , i found a bug, simple bug i think, in player states.
Seems that if you go near walls and try to always jumping, sliding on wall and shooting .. the player remain in shooting state and you can't move left or right anymore.
In other words, there is a case that not reset some states (example the shooting state).
So try to go near walls (left or right is not important), try to jump always remaining near wall and shooting.
If you not success to replicate the problem, let me know and i will made a video that will explain that problem.
About other new features, beyond the two already known previously (touch controls, melee attack), can be the double jump that can be activated or deactivated (for example if you take a bonus you have the double jump feature).
Let me know about!
See you later ...
