I was just about to make another post about this too after spending the last hour trying to find an alternative to Puffin. It sucks that those of us who play on tablet or mobile are partially locked out of an important part of the game for no reason other than that we have a touchscreen. The only method I've seen anyone mention that works is using the Puffin browser, which costs money to use, and apparently is terrible.
I understand its probably not possible to get the current puzzles to work with a touchscreen, and even if it is its probably not worth the cost, but maybe they could be replaced by something simpler that does work with touchscreen? Its extremely deflating to see the third puzzle pop up knowing your gonna get power drain without any ability to do anything about it.
