So as lots of people have pointed out staying in the corners means you are invulnerable… just how? I tried it and often enemies will just spawn there and kill you… Unless you mean about deflecting bullets (which then yes, you are basically immune to them in the corner), there is still a chance to die in the corners too. I could probably fix this by changing up the maps a bit I think, also only major issue I saw regarding corners is that the top-left corner can teleport you outside the main battle area… Hence making you survive infinitely. This is caused by an issue with the shape of the collider I used for the arena bounds which has a very tiny 1 unit gap between points which is however enough for the player to be pushed through it. I will be fixing all this in a future patch after the jam maybe.
