I also got your comment on GameJolt, but I prefer to reply here because I get to use Itch's client software.
I don't mind my game being shoved on the back of your vlog, actually. Gameplay's a bit too short to fill up one video anyway, and I think your content (from what little I've seen so far) is good enough to make me want to see the whole thing.
Regardless, I'm glad you enjoyed the demo to Soluna's Secret. Be assured that I am working on a follow up, and that there will be more game available some time in the future.
In case you were wondering, the tall, slim objects that kept appearing in the lantern's light were crystals, powering the mechanism that opens the door. Don't feel bad about not figuring that out. Nothing in the game so far tells you this. It's honestly something I slapped together at the last minute, and is on my to-do list to spruce up.
I'm also surprised you brought up the story blurb I put in the description. I was starting to think no-one would. It will probably be fully implemented into the game's final version.
Soluna's Secret is not that she had indoor plumbing. Sorry to dissapoint you. Kudos for making me smile.
