The most recent version linked here (v.0.8.03) is completely broken. Nobody responds to gestures or does anything except for react to direct contact like headpats. The only working AI I've seen is the girl behind the bath house counter who will bring your towel out and show you to the changing room. Also grabbing anyone's hand seems to always make their arm snap backwards and it feels impossible to do anything gentle with them. Should probably link the last working version for v0.8 until these are patched since right now it leaves a really poor impression of the game.
Edit: For some reason, spawning a custom card character suddenly had the AI working again (for gesture responses at least) even for the ones that come with the game, but I could no longer spawn characters and the tutorial still didn't function. Still seems to be a pretty buggy version of the game even with this workaround though.
