Adjust light_environment

【 v1.1.3b 】

・Fixed cubemap

【 v1.1.3a 】

・Fixed prop position

【 v1.1.3 】

・Fixed lighting issues
・Added light source processing to some particles (will be removed if it slows down performance)

【 v1.1.2 】

・[Boss] Damage of tetris attack changed to 80
　- If you can't see them, you will be just fine if you can avoid other attacks
・[Ending] Delete ball and laser trails
　- I think it would improve visibility and a little fps
　- If we reduce it any further, there will be many problems, so please deal with them on your own...

【 v1.1.1 】

・Fixed some textures
・Trying to fix the boss's tetris attack not being visible (probably not fixed)

(I can't quite figure out what is wrong with some of the lighting on doors and such)
