Superb interaction between the classic "explore and talk to everyone" pseudo-RPG loop and the slashing mechanic. Timing your interactions with NPCs so that your PTSD doesn't just kill them is completely unique and works super well - you end up doing everything with intent, speeding through dialogue, exploring while waiting... I loved it.
For AZERTY keyboards, use win+spacebar to turn on QWERTY mode and use your "§!" key (on the left of your right shift key) to slash.
