1st Campaign boss arenas with solid enemies/NPCs can push player off arena during boss fight #185
Description
Describe the bug
Any 1st Campaign boss arenas with solid enemies/NPCs, such as Power Critters, Rockets or Resonant Press traps, can push the player out of the arena through the block border. If this happens during a boss fight, there is no way to go back and the no-save run potentially ruined, as blocks cannot be created or destroyed and cannot actually teleport with Chaos Key.
Example: the player happens to get caught on a Resonant Press trap that rises upwards and they are on top of it, it's very little time to react and they end up pushed out of the arena during a boss fight.
Example 2: the player used a Rocket, and as the Rocket lands and they are under it, they are pushed downwards out of the arena during a boss fight.
