Just played the demo. It's pretty good, better than I was expecting. The full game could be really awesome if the scoring system is balanced, varied, and just generally well-designed. I got a 9885 score after a few runs; I'm not sure how people are getting 18000+, but I really hope they haven't already found exploits and shit. I'll throw it in my Goozex queue when it comes and decide if I want it later.
This kinda reminds of Vanquish, which is of course a huge positive. Hopefully it turns out well!
Oh and it looks like the characters and dialog will be indescribably awful. That was some of the worst shit I've ever seen.
edit: got 10k+ but it didn't register on the leaderboards

Fun game though.
