I really enjoyed playing your game although I struggeled a little with the controls first, as the character is moving quite fast. One thing you could fix is that the camera is following the player to slow. It was also sometimes a bit annoying for me that for jumping right or left you had to move first and then press Space for Jumping and it didn't work the other way round. There's a little spelling mistake right at the start where the first keycard is (it says fisrt instead of first) and if you're pulling a turret up a hill the robot looks like he's walking in the air.
Besides these few little things that mostly don't interfere with the gameplay it's a very nice game :)
