I’ve played it. It’s a fun little puzzle game as these things go - not horribly difficult but interesting and complex enough to keep me diverted for a while, and the visuals are nifty.
I got it as a free download ages ago; I’d probably play the sequels but last time I checked they cost more than what I thought the likely value of entertainment gained would be.
One of the possible endings in The Room III involves being transported to the Null Planet…which may or may not be Mars.
I’d like to think that Null is the solid concentrate of Hyperspace/Subspace/Æther, so that opens up possibilities of Null being a significant component of an FTL drive for interplanetary/Interstellar narration of a future edition in The Room series
