Okay. I can see now ^^'
Well, I don't know which buttons you are using, but you aren't the only person complaining about this issue.
GdGohan is trying to find a solution to this problem, in hope that it will be fixed soon.
I used LS(Left Stick) to move but it's using jump and spindash, about pause i used B button.
Well, I have good news !
I managed to test the controller support via BlueStacks, and I indeed found problems with the controller inputs.
And I'm currently trying to fix the game controller inputs. I will update the game soon, probably this weekend !
Ok!
those controllers/keyboard control very similar to the Chinese version of Sonic Advance J2me port(Maybe you can find a Russian pirate called Sonic Evolution on the Internet) but without the d-pad control.
