Well, this one's a great way to preserve your sanity during boring meetings or conference calls ;). The core gameplay is auto running, so the only control you have is jumping. But Nitrome spiced things up by lowering the pace a bit (compared to games like Canabalt) and adding platforms. Also they added various enemies with different movement strategies (homing to you, moving on a fixed path etc). And also randomly chained levels, so depending on the position you exit one level, a random one is chosen from a pool that have entrance in that position. There are upgrades and unlockable characters but meh, the core gameplay's good! Play it online here, Android, iOS.
