Great, simple game. Very easy to learn and very difficult to master, which I like in a game. I assume there are currently server problems, which explains the random loading problems and other players not appearing during the game.
One very small gripe I have is that I would like some kind of keyboard shortcut to restart the run (after hitting a wall), but I can understand if the obvious choice (spacebar) might be infuriating to people who use that key to jump and end up accidentally starting a new run without getting a chance to read their score or upgrade their stats.
