Wow, that actually looks pretty good. Dynamic-ish shadows and everything. But it does seem to have some pretty horrendous clipping issues with the camera, and closing my DSi killed it. Everything screwed up on the screen and it crashed. Weird, the DSi seems to have all these strange problems with cutting-edge homebrew.
...huh, the more I look at it, the more impressive it seems to get. Like...sorta dynamic lighting and everything. It actually seems to look better than your average commercial game, though it's really unpolished...the camera's horrible and clips through all the geometry. But still, I'm impressed. It'd be pretty cool if they could take advantage of external RAM packs, if possible...dunno how it's set up, or how fast they are though.
