About the Game
This is a game about stacking middle-aged men.
Stack them to a certain height to progress to the next stage.
However, not all of them are ordinary.
Some carry treasure,
some are robots,
and for some reason, some even come with bombs.
Stacking them is much harder than you might think.
While enduring the stress,
can you make it all the way to the end?
