About Space Astronaut Puzzle GameSpace Astronaut Puzzle is a 25-stage lost in space escape platformer. Move around space using the WASD keys. You can jump up one row up but can not land again unless you land on a higher platform, run into a ladder, or find something you can grapple onto. Use the arrow keys to grapple onto wooden crates or green blocks. If you are standing stationary on a platform or are on a ladder when you grapple it will pull a wooden crate toward you, whereas if you are floating in space you will be pulled toward the wooden crate. Avoid running into spacemines or you perish. You can pull crates through mines to blow them up without harming you. Avoid running into lasers. You can use crates to block laser beams.
