BlockBeat by voxelv
Noisy arpegiator wants you to build voxel shapes! Spacebar to skip a shape and try a different one. The shape must be centered correctly and vertical orientation matters. Horizontal rotation does not matter (it can be off by 90, 180, 270 degrees). Random difficulty.

But I created the desired shape and nothing happened :boy:
I wanted to get the shape checker working generically (any orientation, any offset) but that's a worst-case O(n^3) problem. I decided to keep the scope down by requiring vertical orientation and centered-ness. Unfortunately that does result in some frustration by players. I wanted to keep it as clean and "literal-adherence to the theme" as possible, so I didn't include any orientation hints (such as a box where the shape must be contained or drawing the axis).
