There is a "delay" because movement happens on a grid. You tell it to turn, it'll turn when it gets to the next grid. It's technically the same on the old games like Nibbles, only then you didn't get the smooth movement between the grid.

The music I looked far and wide for something that matched the action. It was originally even in more sync but I slowed the game down a bit because some of my testers said the game felt a little too fast.

Thanks for trying it out and for the comments.
