Thanks for the comment! I really liked yours - the hex/isometric thing was a cool twist and gave it a nice retro vibe.
It'd be cool if we (or reviewers) could make themed categories like 2d top-down-racing or things like that. I kind of enjoy playing games that went in kind of a similar direction, because the differences can be really fun.
Thanks for the spacing tip - I got stuck in a UI-overhaul rut and didn't get to do as much tweaking on the physics system as I would have liked!
