Good, but it needs work.
So far(I'm not very far into it), it seems like a really good game.
The tutorial popups are helpful, but when you're controlling with the keypad, it seems you have to click out of the tutorial help popups with the mouse? If players could do that with the enter key or spacebar, it would be much easier.
I noticed a elementary usages mistake, though: It's DYING, not "dieing". (Even though "dieing" is a valid word, that is not correct usage.)
I'd be more than happy to proof context for a SEQUEL. ;)
