Yeah it's essentially just a tech demo, all the issues you mentioned arose due to migrating the level to a new project because the file size was 1.5gb and exceeded itch's upload limit. My main goal was to get the combat system working which does work, just not in the version that was small enough to upload lol. Objective is to kill all the skeletons and level up but again the leveling system broke when the project was migrated. I was under the impression the objective was a demo not a completed game. ¯\_(ツ)_/¯
