I'm going to take a step back from the details of bugs or features and comment upon the discussion itself. Annoyingly to everyone, I'm going to be very Elvish, that is, say both yes and no. Here goes.
To those who are saying this game isn't ready for prime time, or that it's not worth charging for because it doesn't work on your system, I get your frustration, but there is a sufficiently playable demo available to give the game a good shake-down, so that you can easily avoid spending money for a product that doesn't work. There is clearly no effort to defraud here; if anything there may be a lack of testing resources, which is not going to be uncommon, given the fragmented state of Windows hardware and software. We should treat our developers with respect, partccularly those who are going to try ande make a full-time go of this, a daunting prospect at best.
I happen to agree that this game isn't ready for commercial release, but I'd far rather participate in changing that, if it's a game I have an interest in than act to scare away said developer with unhelpful commentary.
Now to the other shoe. As I said, this game doesn't appear to be ready for prime time just yet. I'd like to suggest to the developers that, like you did with 3D Velocity (if I remember correctly) you releas a beta test product of the full version of the game, perhaps with a limited time license for testing. This will allow you to crowd-source your testing in a way that no small shop can afford to do in-house. I think you will find that a large majority of people here who will test for you will provide good feedback that you can use to make your product better before a commercial release. Even with a fully functional demo, the fact that you are charging for the game does raise the bar quite a bit so far as expectations go. If I'm going to consider buying a game, then, unless I have some wildly strange configuration, it really ought to work out of the box. I note and approve of your willingness to help users solve the problems that are coming up, but in putting up a for-pay product, you are in effect saying that this is ready.
So, I think that we can all work together to create an environment where this came can improve and live up to the coolness of its concept.
