Hi! Thank you very much :D
Because of the limited time I ended up not being able to program the game for mouse and keyboard, then, as I put there in the description, you need a gamepad to play :(
With the gamepad, the controls are A (for Xbox, and X for ps4), and the analog stick.

As a word of advice, people don't generally read the "short description" too thoroughly. That's more of a tagline for your game and people don't look at it for control information. You should probably put a list of controls in the main body of the game's description for people to refer to. Something like this:
CONTROLS (gamepad only)
Analog Stick - Movement
A(xbox) or X(ps4) - Jump/Shoot
It should be something that people will notice on your page at a glance. Hope this helps!
