Block Man 2

The game introduces a lighthearted, fantasy-themed story. The Kingdom's magical blue crystal has been stolen and hidden away across a series of dangerous subterranean rooms.You control "Block Man"—a stout little character wearing a green shirt and blue pants—who must navigate a series of increasingly difficult levels to retrieve the crystal shards and save the realm. Gravity and Block-Stacking MechanicsBlock Man 2 looks like a standard side-scrolling platformer, but it is entirely a brain-bending logic and physics puzzle. Your character cannot jump very high, meaning you are constantly trapped by the layout of the cave walls.
Block Man can pick up large blocks scattered around the screen and carry them over his head. You can stack blocks on top of one another to build makeshift staircases to climb up steep walls. You can only walk through gaps that are wide enough for both you and whatever block you are carrying. Crucially, blocks are subject to gravity—if you pull out a block that is supporting a stack, everything above it will crash down. The puzzles require perfect forward-thinking. If you drop a block into a tight corner or trap yourself under a ledge, you can easily cause an un-winnable scenario. Fortunately, the game features a quick restart key so you can immediately retry the room.
