Hiya Orkfaeller!
Yes, our pixel artist sude made the monsters in the thumbnail and all of the assets except the fonts. But we had a very short time left and they didn't have any animations by the time they are finished, so we decided to keep our prototype enemy for it would keep our game looking much more polished. Also the game's ending was intented because of those designed monsters.
The low volume music problem was the result of my rush on the jam, I'll add a tuning slider and we are definitely going to change the enemies to those in the next sprint.
tysm for trying it out and the feedback!
