Available for iOS and “coming soon” to Android is “Monument Valley” by USTWO Games for $3.99. Featuring geometric and colorful art “Monument Valley” is a must play game. The only downsides are that the game only has 10 levels and is very easy to beat. I beat this game in an hour so charging almost $4 for this game seems kind of outrageous considering similar games can cost much less and have more levels. But currently the game sits at number 1 in the AppStore so they’re doing something right!
