What a crazy difficult memory game! Though in a good way. It definitely gets the mind working. The first line wasn't that difficult, the second one was a bit challenging, and after that... without reference it's difficult to complete them at all. I tried thinking in patterns, but looks like it'll take some practice to really be able to print these things into your mind. That you can't fill out the colors in the order you remember it, but have to jump from piece to piece at random, makes it all the more difficult too. Truly a test of the mind and memory! Simple functionality for a really clever concept. Nice work.
