Oh, ha ha ha, hi there!
So the Kra'arnauk games are actually "recaps" of D&D sessions I've played with my friends. To keep the campaign fresh in our minds even when we go on hiatus, our DM has one of us write a little summary for each session. I, being me, went ahead and made a Twine recap for two of them.
Kra'arnauk's Battle Simulator came from a session where there was interesting sailing/wind battle puzzle, which... we totally didn't handle well, leaving me spending the entire fight uselessly puttering around in circles. Writing a fake battle simulator where the player can't actually accomplish anything seemed like good practice for writing a real battle engine, someday.
As for the Undertale game... yeah... maybe avoid playing that one. It's weird, because there's actually not a lot it really spoils. It's mostly concerned with post-game stuff you might not find on your own anyway. Yet... it's still better for both games if you play Undertale first. It can wait. Neither game is going anywhere.
And yes, when I do make a new Flora game, I'll post it to the forums right away, don't worry!
