Crystalrect

The two-dimentional platform game Crystalrect is somewhat similar to gravity guy or related games where the goal is to keep running as long as possible. But in Crystalrect you're running on the floor and the ceiling, tapping the screen to alternate between the two.

Unlike similar titles, Crystalrect isn't an 'endless runner' game, the levels are not infinite but have clearly marked checkpoints. Altogether Crytalrect has 18 different levels, each one exponentially more difficult than the last!

If you're unable to beat a level for some reason, the game does allow you to skip levels -as long as you watch a video first- so you are never completely stuck. But be careful, the levels get very difficult very quickly, so it's best to progress slowly.

With elements of Gravity guy, VVVVVVV, and geometry rush, Crystalrect is a fun and frantic platform game that also has decent graphics. And don't be fooled by there being only 18 levels, this entertaining, difficult game will keep you playing for hours.
