Unused Tile Sets[]
A group of unused tile sets (larger size).
These are a collection of tile sets that are not used in the final game. The first three tiles on the left in the bottom-left corner of the grid are obviously from Wood Man's stage. The group of four tiles in the upper-right are clearly intended for Flash Man's stage. It's interesting that they made corner tiles, and could have easily put them in, but didn't for whatever reason. The square in the bottom-right looks like it could've been used in Metal Man's stage. No idea what the Mettool tiles or the black and blue above the possible Metal Man stage tile in the lower-right, though the black-and-blue thing look like it would fit in with background scenery somewhere.
