Never heard of it. Is it a story heavy game? My Steam account says it's similar to Hollow Knight and Ace Attorney, which seems like two completely different games.
I suppose you could say it's story heavy since what you're doing is piecing together what happened on the ship. The story is that you're a insurance investigator and have to find out what happened to every person that was on the Obra Dinn. It's a great game. If it matters, it's a Lucas Pope game, the guy who made Papers Please.
I picked up En Garde recently because I absolutely adore the tone, setting and swashbuckling duelist vibe.
It's a little flat for me, I don't feel like it has achieved the character fantasy of being a swashbuckler in the mechanics, instead I'm basically kicking boxes into people and stabbing them again and again.
