Oooh, you're playing the 2023 demo. That one was almost 1 hour long. The 2024 demo is completely different with only 15 minutes playtime compared to the 2023 demo. :D That boss is long gone now.
is it still in the main game?
Yes, you'll still be able to fight him in the main game but the moves are different compared to the 2023 demo.
