No brain needed
The game had no thought put into it. The levels are basically just a repeat if you can remember 2-3 levels back to back then you are good. The only thing that changed was the coloration. I thought it would actually be a tough game but it was easy got bored and deleted it after like 5-10 minutes. Once you play it for like 5mins you will know why I say the levels are a repeat of previous levels.
