The game started off way to strong. I an tell that this game draws inspiration from Mega Man, but the levels in those games always have a slow ramp up in difficulty, and they will never throw multiple mechanics at once at the player without teaching them in isolation first. I recommend polishing up the movement some (the player should either accelerate a tiny bit before reaching top speed or slowing the player down some.) Zooming in the camera a bit, and working on level design.
Also, I couldn't reach the second screen because the lazer insta-killed me every time.
