I'm enjoying the vibes here, but I think you definitely need to do another proofreading pass -- in addition to the issues other folks have mentioned, it seems like the text for Operate and Tinker is the same, and Cook and Sharpen have the same "flavor text", as do Ritual and Research.
Further, did you...change the name of your game at some point? In a few cases, it seems to refer to itself as "HSS"?
I also found the explanation of tokens somewhat confusing -- some are applied to characters and some to leviathans, but it's not clear to me if you "spend" tokens on yourself or on your target, and whether tokens on the target are "character specific"; If I apply Target to a part, can someone else use that Target to attack?
I could also really use a...checklist? Bullet list? for how Leviathan actions should go.
Looking forward to future revisions!
