Bat Outta Hell is now playable on mobile. Not gonna say it's perfect, but the start is there. It supports tilt steering. It calibrates after a short countdown when you hit start game if tilt steering is on / available. On iOS, this requires accepting a permission. Touch gestures available if you don't wanna use the tilt steering. I probably need to run through the how to play section and do some updating, but controls are:
Swipe up / down: Throttle
Flick left and right (when tilt steering is off or unavailable): steer
Two finger single tap: Activate power-up
3 finger single tap: Pause / unpause
Two finger up / down / left / right: Announce various bits of info
These work on most of the playable area, but two vertical strips on the left and right are dedicated to the horn / horn ball.
On iOS and Android, touch controls are unavailable unless screen reader is off. Thus, there's a use TTS checkbox in options. On iOS, every time the TTS fires, it significantly ducks audio. This is far from idea, but completely out of my hands. I would therefore recommend becoming familiar with the game / sounds on PC or Mac, then turning off the automatic speech announcements on mobile once you know the sounds well enough. This will still let you use the two finger swipes to get info.
