This game is pretty neat. The movement system is pretty interesting and can be fun to use. The controls are a bit finicky with how many bumpers/triggers you have to press and hold at the same time, but I imagine that's kinda what you're going for. It's like Bionic Commando meets QWOP. If you're going to expand on this game and want to streamline the controls scheme, as a rule of thumb, I wouldn't have the player use the bumpers and triggers simultaneously, as that requires extra fingers. Maybe you could combine the functions of the left trigger and bumper, so I press the button to call my arm in and release it to shoot it out again (or maybe the other way around). Also, grappling would be easier if you could grab things from a greater distance as the timing window is pretty tight currently. Despite these issues, this is a really interesting premise and it would be cool to see this expanded upon, perhaps with enemies you could punch with your arm, but what you have here is promising. Great work!
