It would be nice having the level automatically restart if you get too far out of bounds. Or perhaps a VERY clear indicator when you are out of bounds that pressing R will restart the level (that includes the main menu)
When I first played this game, I thought "Ugh, just another Canabalt clone. Nice graphics, but still another clone."
But after playing this game, I realize that they are not so alike after all. While Canabalt is solely based on distance, this game is point based, and the distance traveled matters very little. Extra or 'close cut' jumps REALLY pay off if you are willing to risk it. It adds an extra layer of strategy and choice compared to most jumping games.
It's a very neat idea, but just doesn't seem like enough.
It needs a twist or something, some way to make it more appealing than holding down A (the shoot key) for half an hour and moving up and down to avoid bullets.
