Update 1.6

This is a big update. So first change is that all the backgrounds have been made more vibrant. I feel like this was needed as they were quite dull. Secondly, the animations have been made smoother. Third, all the music has been updated slightly. Fourth, Chromablitz mode is back! The gimmick is slightly different, where you have coloured bricks which you must destroy using the same colour gem, but close enough for it to be the same mode.

Plus a few smaller bug fixes and things.
