It's quite impressive to be only 96KB.
I saw some very small (filesize) 3D demos in the past (like 75K), but this is an actual game (fps). There are still some bugs left, and the gameplay is not that good, but it is definitely worh the download size
. System requirements are quite heavy, though, since all textures etc. have to be computed; so it takes some time to load. And you need a gfx card which supports pixel shaders. The graphics are quite good, some nice lighting effects etc...
