Bomber Man
Bomber Man here is the crate-pushing puzzle kind: 70 built-in levels of pushing boxes onto target points, sorted by difficulty, plus a Level Editor to build and share puzzles of your own.
The rules never change — push, never pull — which is exactly why late levels get vicious: one crate against a wall is a restart you'll see coming three moves too late.
Tip: before your first push, find each crate's final corner and work backward. Sokoban rewards planning the ending first. Kindred puzzles under block games.
