Cool, came here to report the exact same bug. Twitching, and doing the down smash eventually caused me to warp through the floor and initiate an endless fall into white nothingness. [Edit] After exploring some more, the extents of completeness are more obvious. I like the design style, and the art is very evocative. In terms of gameplay, there's a lot of blind jumps that basically end in death (spike and lava rooms to lower right). While I like the quick save mechanic with the light pillars, telegraphing those rapidly changing hazards might be less frustrating. Also, is it currently possible to get to the stuff up to the left?
