Sorry about the controls. I'm using my old engine from 3 years ago, and I can't be bothered to change it. Must follow the tutorial. Everything is there. Gun instructions will be shown under the ammo bar. Arena guide: lv1: Boss is immune to all damage. It can only be hurt when stuck in the wall. When the boss reaches a certain HP, it will heal. You can prevent it by activating an alarm at the top of the map by pressing q when the boss is healing. lv2: Boss heals when it hits you, rain makes an electric attack from the boss deal more damage, hide behind an obstacle when boss jumps to prevent shock wave damage.
