Endurance Testing Initiative
A downloadable game for Windows

Endurance Testing Initiative is a Portal-inspired game where instead of portals, you advance through testing chambers by giving up your freedom.
- Cuffs, shackles, blindfolds, gags, collars, and Harnesses will restrict you through the levels.
Planned restraints include:
- Bitch suit
- Shock collar
- Liquid latex
- Null bulges
- Mummification
Planned features include:
- Butt plugs and vibrators to distract the player during tests
- Aphrodisiac gas
- Patrolling “Fuck Robots” (“Because who builds a robot you can’t fuck?” -Grivik)
- Customizable character creation (This one is a maybe. I have to figure out how to do it.)
- And much more as I think of things!
