Game in a Bottle is the developer of the GemCraft series, a long-running tower defense line that began in the Flash browser era and built its reputation on gem forging and fusing rather than fixed tower upgrade trees.

In October 2026 the studio released GemCraft – Legacy Collection on Steam through Armor Games Studios, gathering GemCraft, Chapter Zero and Labyrinth with modern speed controls and hotkeys. It charted at #24 on the Steam 250 weekly list with a 94% positive rating from 108 reviews.
