I really loved this! The feel is amazing and I love the use of screen wrapping to extend freedom of movement while keeping everything in a manageable space. The learning curve was just right to keep me feeling challenged and the game left me wanting more.
If I had one complaint, it's that the targets are just a little too small, at least for the early levels. It might help to start them a big bigger (or otherwise easier to hit) and shrink them as you go along, considering how tricky it is to get really precise movement dragging a mouse. A few times I whiffed a straight shot on a stationary target I was sure would hit.
The conveyance was great, btw. It's easy to tell at a glance what's going on. The way the ship not only goes dark but bounces around like a normal object until you regain your boost really sold the out-of-control feeling. Really solid game.
