Block Dude Deluxe

Block Dude Deluxe is a free, single player, keyboard-controlled puzzle game.

In this game the player controls the titular Block Dude and takes him from one part of the level to the exit. Along the way Block Dude has to scale walls he cannot jump, and to accomplish this the player must carry crates around and stack them to make stairways. The early levels are single screen puzzles but later levels are larger and the screen auto-scrolls left/right as Block Dude explores.
The game is level-based. Once a level has been completed, the next starts automatically.
The game auto saves on completion of a level and records the player's completion time.
