I own a copy, and I haven't had a lot of time with it yet but it looks like it's got the potential to be a blast. Also, it's actually free advertising for the developers, so hopefully this helps build the game community so it can thrive and grow. I'm far from able to make a judgement, but if the game delivers on even half of what it promises, I'm going to love this so much. So much so that I fear I'll have to get myself a joystick a lot sooner than I'd expected.

Usually, when an indie game is priced at $20-25, you should expect work equal to a $40-$50 AAA-budget title from a big publisher in terms of attention and care, along with the attention that the community is able to get from the devs (in terms of support as well as relationship, being a smaller and more manageable group and being that much more critical to a small dev team). It's not always true but it's my rule of thumb if there's no obvious quality flaws from the looks of things. So I figure I'd do my part to encourage things I like. :D
