I can't play, the player is locked to the left direction, and I can't move when the player reach the left side of the arena.
I tried the tutorial, solo, and vs bot, on tutorial I can't complete because of this, and on solo, both players go left only(alone) .

I tried here and on Kongregate versions, both on Chrome browser. Also tried on Itch Desktop.

So that sounds like you have a controller, or maybe a steering wheel plugged in. LazerGrrl has controller support, so it will pick up inputs from controllers
