!!! some of the star wars ships in the second space room had an error when porting and their hitbox is broken and is far longer than it's supposed to be. That's why the room is a lot longer and it's covered full of lights to let the ships glow in the dark. One of the ships is still dark; I'll try to fix this in the next version, now it's covered with fire particles.

changes:
- removed the endless stairs and replaced with a blue lava zone arena
- added particles
- added sound effects "another happy landing" and "hello there"
- added more details to the map

Updated download source. The version of the map should be a5.
