ClickIt

ClickIt is a simple game in which you have to convert 16 tiles as fast as possible by clicking on them. With every level the tiles revert faster, which means you have to ramp up your clicking speed in order to keep up ;)

The game features two modes: Time Mode and Click Mode

Time Mode

You have 10 seconds for converting all tiles, while the revert frequency of the tiles increases by a couple of milliseconds. This might not sound like much, but these few ms are noticeable quite quickly ;)

Click Mode

You have a total of 32 clicks for converting all tiles, while in this mode the revert frequency increases as well.

You can choose between four difficulties when playing in Time Mode: Easy, Medium, Hard and yenoh

The first three may be self explanatory, "yenoh" is by far the hardest setting, courtesy to a friend of mine who thought Hard was still too easy ;)

Furthermore, you have the possibility to get away from the plain red and green tiles by activating the "Minion Mode". More such themes are planned, but feel free to let me know which ones you'd like to see within the app's XDA thread:
