I haven't been active in forever, so forgive me if this sounds like spam (I mean, it kinda is, hmn?).
Anyway, I have been developing this game - "nous." for about 10 months with an engine that is not to be named. It's a simple, minigame based, single- and multiplayer game. Your objective - Hold out as long as possible and conquer the highscore lists! Different types of mini games in three increasing difficulties are waiting for you: crunching numbers, memorizing and estimating things, reaction and speed tests. What will you do best?
The base "nous." is free, and has a little ad bar, but is otherwise full featured. "nous+" does not have the ad bar and costs 0.99$.
It would be really cool if you could download and maybe even rate the app, direct links are available below. You can also check out the website - http://nous-app.com/
