New Game - 1000 Heroz
It is not really a new game because I have been playing it for a while now, currently Day 38. You get a new level every day for 1000 days and you have 24 hours to set a fast time on that level. Your character has to run to the finish line whilst jumping over obstacles to set a time.
You can then check your time against the global leader board or even better set up your own custom league to compete against your friends.
Special mention must go to the Day19 (Yes I'm biased)
