I have so many things to tell you but we will try to get to the point.

First you should check the wiki
https://github.com/corentingosselin/ProdigyNightclubWiki/wiki
If you want to know which features are added

Yes I have removed old features with effects, particles, dancers
It's only temporary, I will add more in a few weeks

Please help me to test, and report any issue you find !
Have fun
