I have done a couple of tests, but the controller seems to have issues in multiple scenarios (keyboard emulation seems to be working fine):
1) tested the run in desktop mode - A B gamepad buttons doesn't seem to work, so rotation doesn't work, the rest is fine.
2) tested in steam big picture mode, the appimage was added as a non steam game - left only worked on the d pad and right only worked on the left stick, though sometimes left refused to work at all or worked on the 3/5/7 press (this behavior is random) (Once a game is added to the steam launcher - steam input can be used to emulate different type of inputs, for this example gamepad with joystick trackpad was selected.
3) in both cases, I have changed in the game's settings from keyboard to steam virtual machine - and every time after I have tried one game and went back to the settings, it would reset back to keyboard.
I couldn't really find a working solution with the gamepad, so leaving the game as a non steam game (as I would prefer to use it this way), I have found the following solution - change the steam input (for controller settings) from gamepad to keyboard(WASD) and mouse and in game reassign some buttons.
