On the second screen, I tried to use an ad-infested free QR scanner I already had on my Android, and I had so much trouble getting it to work that I blinked and then the QR wasn't on screen anymore. Idk if that's intentional but it happened twice.
Then I teleported or fell into the water in screen 2D and now I can't get out by blinking or platforming, blinking didn't do anything and I apparently can't jump high/far enough.
Maybe I'll try again, the blinking is a cool mechanic, but it seems like there are bugs and the QR gimmick makes things very difficult. I guess you were trying to make the mechanical difficulty and time delay of using my phone part of the difficulty/frustration of the blinking, and I'm not sure I vibe with that in practice.
