About Marble Factory
Build the factory. Launch the marbles. See what happens.
A physics roguelite about building a machine, then losing control of it.
Bumpers, Teleporters, Dominos, Magnets, Black Holes...
Position decides everything. A machine two slots over changes the whole wave.
Upgrades, talents, machine Mods, Factory Tuning. Every wave hands you another decision.
The build you have on wave 15 is rarely the one you planned on wave 3.
Pick a Core. It shapes every marble you launch, and every machine you build around it.
You line up the shot. Everything after that is consequence.
The challenge is not to remove the chaos. It is to build a factory that makes use of it.
Hard Waves bring Mini-Bosses onto your board.
Bosses change the rules entirely.
Build Combo, land crits, stack multipliers.
A wave that asked for thousands can hand you millions.
Then it asks for more. Your factory has to keep up.
