Would it be possible to have two power ups happen at once. Let me explain. I'm making a side shooter style game, when I get a power up everything speeds up so you fly faster and it looks nice. Problem is that you will most likely die when things are going really fast. So Id like to add invincibility to the power up. Is this possible? Or would I have to add two power ups on top of each other and make one of them opacity = 0?
