About GemVenture

Platform: NES
Developer: Tom Livak
Year: 2009
Genre: Puzzle, RPG
Players: 1
License: Homebrew

Tom Livak's match-three duel modelled on Puzzle Quest: Challenge of the Warlords, made for the 2009 PDRoms Coding Competition.

You and a monster take turns swapping gems on a shared board. Matches fill mana pools, and mana pays for spells such as Fireball, which clears a three by three block, and Lightning, which clears a column. There are 6 character classes, 18 spells and 20 monsters, from giant rats and zombies up to demons and a dragon, and wins raise your stats and level.

Livak showed screenshots on the NESdev forum during development. Venus Patrol called it an 8-bit Puzzle Quest that captures the spirit of Infinite Interactive's game. Retrozone later published it.
