Heh, I didn't expect these to leak out of my bbs so fast. I'm working on a teaser video which includes in-game footage, so you can see it in motion soon. I'm pretty excited about this game -- it's so much fun working with voxels, and exploring the gameplay implications of having a very deformable yet readable 3d world.
Seth -- I also wish it wasn't an arena game and that you go exploring. I started with another very epic and adventury thing, but decided to do voxatron now just so that I can get a voxel game out of my system before tackling a backlog of other projects.
Voxatron does have a bit of exploring though, in a knightlore kind of way. There are multiple arenas, each which focuses on a different style of play. One of them has connected 'rooms' containing action puzzles and scripted monster entry.
