How many GB is Invasion of the Mushroom Men of Planet Y!?

2 GB

That is less than the typical Role-playing (RPG) game, which needs about 6 GB.

Leave at least 8 GB free: games need headroom to unpack updates.

The figure is the storage Steam lists as required for this game, not a measured download.

This is a quick, goofy game that lasts about ten minutes per play through-unless you choose wrongly-organ music, please! In addition to your choices, there is also the random element of chance that may affect your fate. Due to the constraints of the game engine, can only be viewed in windows mode.
