I wanna say that I love the fact that this game has separate keyboard and joystick modes, and that commands (like movement) aren't being forced on my controller, just because there's a controller option.
The keyboard defaults are horrible, but then again, this is the kind of game I would only play with a controller, so that horribleness doesn't actually matter.
This game is super-cruel. The beetle moves very fast, and there's not a lot of terrain to run on to catch your breath. A lot of times I'm failing, not because the beetle fell into water or a pit, but because of a bump in the path, which seems like kind of an undignified way to fail.
Overall, I like what's going on here. I wish some easier levels were tucked into this package, and I like the idea of paying for a longer (and possibly slower) version of this.
