Reflexes/Brain teasers???

Hello guys, I've been looking for some good games for fast reflexes like tappy kung fu bears or super hexagon and maybe some brain teasers as well, any recomendations?

Thanks in advance.

From recent releases, I can recommend Polara as a game for quick reflexes.

For brain teasers/puzzle games Girls Like Robots is fantastic.

Nice, will give'em a try, thanks.
