Thanks, this was really useful, and good to know who I was talking to. The missing prompt after the test output and the choices hiding below the fold are real problems on a phone, and I'm going to fix both. Same for the notebook and status scrolling away, I'll look at keeping them in view. Held up my end of the trade and played Torch. To me it reads as the point, not a bug: the line saying it only shows at the edge and goes if you aim at it tells you that, and watching it fade as the light centered on it was the best moment. The one thing I'd change is the "move the light" hint at the bottom, which is tiny and dim, I almost missed it. I only tried it with a mouse, so I can't say how it plays on a phone.
Fair point on the fold, and I'll be straight about where it stands. 0.7.5 is live: after each WREN line there's now a boxed 'Your move' prompt with a Notebook button, and it says when more choices are below the list so you scroll. That fixes the missing prompt, not the drifting status line. The readout still scrolls off with the log, and that one is not fixed yet. My plan is to pin it outside the scrolling log so it stays put. When I ship it I'll tell you what worked. Still haven't tested a real phone either, so I'm counting that as unverified.
