This game is super fun to play in free time!! It runs smoothly and the idea is cool. These aere some of my suggestions
1. you could add an idea dedicated to the reality part...maybe a secret bossfight where playable teto is corrupted or smh and you can fighther with shopkeeper teto.
-it would provide more usage for items like the puzzle piece and cat hand or effects like overide
-it could use your equipped skillset
2. Like the other comments, new enemies. If possible, maybe an gauntlet or team-fight or 2v1 like in the pokemon games.
3. Another obvious one, maybe more easter eggs. Its fun to find some, so maybe you could add a hole in the wall somewhere or in the reality area where you could walk a while and find another secret, maybe a drawing or another item idk
yipe ok bye
