I know how to split and shut off shields but it's still way too hard to dodge enemies when your other half cant make small evasive maneuvers. I've noticed you can use the gun to shoot him other places but when you have bats kamikazeeing towards you youre pretty much gonna have to run back into them to go back onto that platform. A much needed fix would be full control of your other half while using arrow keys or a jkli format. I like this game and it would be awesome to have more of a shot of beating it with skill instead of just random luck by not rng.
-edit
Of course its right there in the instructions... I take some of my critique back the best way to play the platform levels is to keep the white guy on the platform and shoot the black guy to the other one if youre fast enough you can shoot him to the other platform and back before the enemies get to you so yea controlling the other half isnt needed but still invincible kamikazee enemies are a pet peeve of mine it seems like just making eyeballs invincible would make things more balanced.
