Thanks for a long review!
1. Actually it should just exit the game. But yeah I've checked it, there is a bug.
2. Thanks for telling me that. It's not intended. These are control settings: on swipe up you open a log, on swipe right you rewind back, on swipe down you hide/show UI. I think I'll change that in the next version.
3. Strange. This doesn't happen to me.
