Use WAD or arrow keys to move. Press E to shoot up. You have a limited amount of shots. (Scroll down for more info) Tips: Use shots wisely. The perfect time for usage is when Mecha Ring opens his arms, giving you the chance to shoot the orange core. Get shots by collecting boxes that glide down slowly, before they plunge into the water and vanish! You may encounter small Mecha Rings on wheels, called Mini Mechas. They will roll towards you, so jump over them to dodge them! If you want to shoot above, do not walk (Jumping is allowed). If you want to shoot left or right, walk in the desired direction. (If you do not want trouble from the small robots, make sure to shoot Mecha Ring all the time!) I deeply apologise if the game is buggy.
