Very addicting, few things of note though. It'd be really cool if the layout of the map was randomized each time you reset, and since the enemies can lock onto you through walls it means that you can cheese them by sitting on the other side, waiting for them to shoot and then coming around. Lastly the game is a lot more fun when you're moving super fast so my recommendation would be to increase the speed of the player at all levels. Overall though it's an extremely fun game that is really hard to put down.
