Glad you noticed that I tried to use the theme, I thought that it was too abstractly implemented for people to notice. :P
And thank you for the double use of very in "very very fun". When I was making the game and I gave it for someone to test it, they felt it was boring. I was already working on it for 2 days and that saddened me a lot. Then I made one simple adjustment on the difficulty and the same person thought it was really fun. In the back of my head I thought that maybe the person was just saying it now to try to cheer me up, so comments like yours make all my effort feel totally worth it :)
