It is the gun that I have a problem with. It does not aim where the mouse is located. Instead, I have to wait for the gun to rotate and point to where I want to shoot. I don't know if this is intentional or a bug.
I found a problem with the rooms with enemies because the gun is not responsive. The gun rotates around in a circle which forces me to move back from the enemy to gain time for the gun to rotate where I want to aim. The problem I encounter when moving back are the blocks make you stuck because it requires a gunshot to move them, but it takes time for the gun to aim where I want to shoot, but I am already trying to aim at the enemies in the opposite direction of the blocks so I get stuck.
I need to be honest. The gun rotating independently of the mouse is frustrating and makes the level not work well.
The healing feels clunky during a fight and when not in a fight. Sometimes I can't heal because the green circle is stuck in the wall.
