Nice game, really liked the mech design and the retro style to the music and audio. I think the camera is a bit buggy, from what I can tell you can only rotate it based on how far your mouse can travel before hitting the sides of the screen. Might be best to use a mouse delta position for camera control rather than what appears to be a mouse screen position? This way you can also hide and lock the cursor to the screen center for better immersion.
Great work overall.
