Very original concept and very inventive. I have an astigmatism so I couldn't figure this stuff out (couldnt ever get stereoscopy to work for my degree). I forced my partner to play though and they had a blast.

They made it to level 2 on the bear game, which strained their eyes but was definitely doable. So the tutorial definitely works and so does the gameplay.

will def keep this on hand as its  a pretty polished and well-explained tutorial evidently, so kudos to you for that and grats on the release

Haha. Cool. Always liked this effect.

That's a bit harder, when you can't initially see an object. But I assure you it's possible.

Cool submission, the hard part for me was getting the things consistently and I still can get very consistently, I don't know if I am to close to screen or what, maybe  later I will try again. And the bear minigame, it says that you need the 3D vision to tell which cone is fake, but you can tell without the vision if you pay attention,  I got to level 3 this way
