Tricks I intended: Exploding an in-progress stacker early enough so that the maximum height is reached in order to make a splatform for those coming from above, building high enough on top of a stack so that you can reach the structure in the upper left, and finally building in such a way as to block anyone from following the builder and then to bomb away a pixel of the staircase to release them with a well-placed bomber. In the end, if you follow the intended route, the timing of the platformer coming from the right at the top and the builder coming from the left should meet at the right time so that the platformer can catch him with a stacker. The interesting thing was that I originally was aiming for a 3-of-everything level, similar to Icho's R1, but then once I realized the difficulty of enforcing that builder trick at the top, I went further and decide to make puzzle revolving coming from both sides at the top so that you cannot get to the other side without platforming from the right side. Near the end, it nearly became a 4-of-everything level except for the bombers, where you only have 3, but then I realized wait, one could just bomb through the platformer that you did over the exit to reach it later, and thus it still ended up perfectly as a 4-of-everything

The main purpose of the bombers are to basically just explode the terrain added by the constructive skills instead of the normal terrain. However, the only time you can explode the normal terrain is at the bottom left and possibly the small wooden staircase near the exit if you wish but of course that's not required
