Thanks! :D
I bet someone can do it! :P

Definitely good questions scarface

the checkpoints are circled so you have to make a meaningful choice between breaking your multiplier or saving your game. If you were going for points, then you'd never really want to circle a checkpoint when you could buff your multiplier. Of course, not saving at a checkpoint is a risky affair ;)

The screen speeds up to increase difficulty. I admit that we could have done a better job with the speed though. However we felt that speeding up the camera would increase the tension at the end and make the end of the track feel more like a boss. Kind of like increasing the stakes, ya know?

The screen is essentially the main antagonist in the game. If the screen were to move with you, you'd have no trouble manuevering through the level, at least a lot less. You know those mario levels where the screen moves at a certain speed and you have to stay on screen and if you don't it catches up with you and you die? That's the basic idea. We felt like having traditional enemies or other adversaries in the game would have been more out of the spirit of the game.

The labels kill you for the same reason the camera kills you. Without threats like that, there would be zero challenge. Though we have played with the idea of doing another version of this game where the game was a lot less hectic and more about exploration.
