Treasure Huntress: Super Sapphire Sisters is an action-adventure game inspired by games such Tomb Raider, Metroid, Freedom Planet, Sonic Mania, and Alien Soldier. The game features both a rich single player and a cooperative multiplayer mode, with transfer-ability of data between devices (Such as Mobile, PC, and Console), as well as broad multiplatform support. It is written using a custom engine entirely in very basic HTML5, using no WebGL. Despite this, it is graphically modern compared to most 2D games. It is planned for release on most major platforms by mid-September of 2018, with the hope of publishing it to the Switch.
