So was this the case for everyone or just me? I never received my physical kickstarter rewards for this game.
Physical rewards haven't been shipped yet, as they're still being manufactured.
Your digital game keys were sent to the original email address you pledged with via Kickstarter. It appears you have since changed your email address, so I've updated to use your new email address and you should be able to access them on Humble Bundle. I've sent you specific details in reply to the message you sent via Kickstarter.
Same here...for the last 5(?) years I check on Kickstarter every few months and see no progress. Figured I start checking here before I give up completely.
