Hey, just a quick question on the topic of the 4 Colour Rule:

The unity splash screen is more than 4 colours and I can not remove it as I'm using the personal edition, will this break the rules? It would be impossible for me to submit if that was the case :( 

Yeah, that's fine :) It's a limitation of your engine. Make sure you submit a recent version - you've got right up until the deadline to update your files!
