Small studio.
Big claws.
Grizzbox is an independent game studio with a foot in two eras. On one side: modern Windows games with all the comforts of today's hardware. On the other: brand-new software for the 8-bit home computers and consoles that started it all.
Writing for an 8-bit machine means counting every byte and every cycle. That discipline shapes everything Grizzbox makes — tight controls, readable screens, no filler.
— Made with stubbornness & too much coffee.
