Do not lock enemies behind doors
Do not layer enemies, bounceblocks, or gold. By that, I mean don't stack stuff like gausses on top of each other, and don't stack gold on each other or bounceblocks.
Do not put more than 1 ninja in a playable map, ever. It messes up demos and is just useless.
Do not hide enemies like mine under gold, and don't hide stuff like enemies or keys under bounceblocks.
Basically, until you are a very devolped mapper, never hide anything under anything else.
