I was able to play a little of this in beta and really enjoyed it. It takes some getting used to and it's not as polished as a AAA title but I had a lot of fun. It's an almost free-roaming endless runner with a really crazy hazard system. When you get a good run going and you're dodging meteors, jumping chasms and avoiding falling tiles by millimetres it's quite exciting and original.
It's by the creator of Lonely Bunny too so you can be assured that the dev will listen well to criticism and implement fixes and changes the community suggest. The IAP system is for single use boosts and any one purchase removes ads, there aren't any energy bars or times thankfully! Definitely worth trying as the devs has some awesome plans for future games that deserve to be supported!
