I am using state machines for the boss AI, yes, and a new scene loads between levels.
I was pretty disappointed to find out that it seems like people just farm ratings by spamming their game everywhere, and I'm really not someone who is on social media much at all, so that really doesn't work for me, so maybe its not that big of a deal that Im not really in the voting. Im just glad I walked out with a finished product, and like you said, if someone happens to find it and likes it, that's good enough.
