Fun little bug I found. Just keep tapping the bottom “back” button over and over. The UI continually shrinks down, getting smaller and smaller until it’s no longer visible. It pops back to correct size when you stop tapping back, but the back button should probably stop functioning when you’re at the top level.
We left it in on purpose! I can’t articulate exactly why, it just amused us thinking of who would do it because we are also the kind of people who would tap it repeatedly and break it. Good place to check when we eventually add secret rewards.
I’d noticed this too and had the same thought. Fun to make the entire UI zoom out to nothing for no reason. Put me down as a vote for secret reward on this. I mean, not ahead of implementing sync; got to give the people what they want.
