When I downloaded this game it said it was only 118MB. However, after playing for just an hour this app had used 1.65GB. I checked the app thru my phone settings and it says 1.60GB of my storage space are being used by this app. I'm very disappointed by this because I would not have downloaded it if I had known how large the app really was. The game can be fun, however it seems that I spend more time being taught what to do than actually playing the puzzles.
