Vasco Freitas is a very talented game designer from Portugal. It is hard to get a game right, by which I mean get a game to be exactly the right balance between challenge and fun. There is some kind of psychological effect going on. Flappy Bird had it, and so do Vasco’s games.
Check it out for yourself. My suggestion is to definitely try Freeway Fury 2 and Gswitch (both on Desktop and Mobile).
