As to black box, check the db. I do enjoy black box, but I confess some of the puzzles have me reaching for the hint cards a wee bit too often, especially when the hints aren't that helpful, or are pictorial, I also sometimes worry I might do something bad if I mess with my phone too much.
I'm not sure what one two switch is, but I do like dusk though I admit I wish instructions were improved or you could have a little more information.
Tap tap is rather fun, my best so far is 20 taps at 3.1 per second but we'll see.
ping pong is a little disappointing, since I was hoping it was more a serious pong game with sterrio targeting rather than rhythm action, still its fun to use my phone like a tennis racket.
Bubble I really rather like, once I worked out to stop when I found the vibration and tap to burst, its not original but its a fun execution and I always enjoy haptic games.
Flag I like the principle, but basically it seems I am okay until I'm asked a compass direction. Even when I spin round it never seems to pick up the cumpas correctly. The game should have a cumpass test setting to let you know what direction is where (I tried using the Iphone compass but it didn't seem to help).
Safe opener I don't get at all, you seem to need to turn the phone vertically to get vibrations, however literally every centimetre I turn the phone I get a click, holding it does no good, I just turn and it goes click click click, indeed the game hasn't even finished on me. Oh, and I've got an Iphone 8 so there are no compatibility issues.
I would be willing to pay for more games myself, but I'd prefer to see improvements in those we have, EG a more efficient cumpass testing for flag and some actually helpful instructions for safe opener, indeed instructions for all the games could be improved for sake of clarity, particularly if the idea is to appeal to sighted gamers with haptic or audio based games.
With our dreaming and singing, Ceaseless and sorrowless we! The glory about us clinging Of the glorious futures we see,
Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
