Just released my new game recently, with the intention of it being a game which is as addictive and frustrating as Flappy Bird but with a very different gameplay. It's a minimalistic game which has the same sort of 'simple' concept. You just move around a Cube and try to collect black boxes. It's also completely free! Would love if anyone would check it out, possibly get addicted, and then share with their friends.
Also, there's a contest going right now for 2 x $10 iTunes gift cards for two people that review it! You can find out more here,
