Space is Key 2 is a Flash game by ChrisJeffGames and is a sequel to Space is Key. Space is Key 2 features five new levels with sideway platforming style (for a total of 20 levels) and a new Challenge Mode which contains 10 levels with significantly increased difficulty. Similar to the previous game, the only control is jumping. You control a block moving at a constant speed, and the goal is to get from one side of the screen to the other. Jumping is done with the Space key, but it is always at a constant height. As you progress, there will be walls and obstacles that you will have to jump over or dodge.
Walgrey completes a deathless run of this game in record time.
