Don't sell yourself short: it is genuinely a good game. I'm a pretty thorough play tester so I'd have picked up anything else that was massively wrong (I don't think there is anything, as far as I got).
I assume that minor corrections are fine. I hope so, as I've spotted lots of little typos here and there in my own game and have corrected them and uploaded a new version of few times. Substantive changes, though, should not be allowed.
