Mighty Switch Test! 2! (out soon) is set in a series of discrete bits of blown apart spaceship, where you navigate from one to the next by using an airboard and bubble shield to get through the vacuum of space. That's taken from this 2005-era draft. Also featuring a cool sequence at the end (if you skip the inviting-looking tube) where you have to shoot destruct scenery blocks with the right timing to avoid death.
