Tortal! is a fusion of Nintendo's Super Mario series and VALVe's Portal. It features a level editor, 35 test chambers + much more additional challenge chambers and plenty of obstacles; laser grids, mechanized koopas, turrets, cannons and firepits. Ally up with your friend in cooperative mode or solo the campaign, meet GLaDOS and help Chell escape the facility.
Tortal! is now abandonware, here's the latest build with the old 3 levels. Project is discontinued under further notice.
