I played this at Eurogamer and got hooked, it's incredibly fun, challenging and addicting. The idea is to get from 1 end of the map to the exit, there are multiple route to take and not all of them are right. You go super fast but limited energy and different enemies and obstacles try and stop you. I spent a good 30 min on some of the levels before I finished them. Think of it as Mirrors Edge mixed with Mega Man.
