I really like the concept, and the use of the numpad is genius! It's weird to say, but it almost feels like a flight sim or some other thing where you control something complex: with one hand on WASD and the other on the numpad. That said, I struggled quite a bit with the controls, I seemed to move relative to how the character was facing which could get really confusing given the fixed perspective. After the second level I wasn't able to progress any further: the enter key didn't work, but I think the idea is definitely there! With some more work this could make a fantastic game!
