Superb, Brilliant, Ingenious App without advertisements! Gorgeous, Bright, Uplifting Colours! Thank you very much, Dev, for your brain game! This should be rated as 5 stars as it gives your brain a great workout but not your wallet! It is much appreciated that we are not forced to pay for levels, etc in your other version. There are NO advertisements popping up or taking up storage space. For this reason, I am gladly upgrading to your Pro version for this app, which also takes up only half the space! All the very best, Dev! NOTE: For those who want to start on a new slate, go to SETTINGS, APPLICATIONS, COLOUR OIL, and then erase its DATA.
