Great game
Love the game but Middle Level 34 has a glitch so it's impossible to pass. Update: I ended up just paying the 99 cents to go to the next level, since the Middle Level couldn't be passed because of the glitch on Level 34. Now Hard Level 21 has a glitch too, where whenever you try to enter a color the game shuts off. Definitely don't waste any money on in-app purchases, as you'll just run into bugs in the game. I was so excited to see the update but none of the bugs I ran into were fixed. Another update (5/15) and still the bugs are not fixed! Yet another update in Oct 2015 and still no glitch fixes.
