Thank you so much for your feedback!
I think you got stuck because you couldn't find the entrance. The garage can only be entered inside the house, and all doors outside was intentionally blocked.
I've got lots of people complaining about the collecting books process. It was made fairly early in the game development, like last year, and I wasn't sure about what this game should be about so that scene is just me experiencing with Unity. Sorry for all the stupid ideas I made! I do plan to make the process a little faster so you don't have to crawl through all the classrooms, as well as adding more elements.
The dialogue disruption was a bug, it was originally just a background dialogue that doesn't interrupt anything, but I changed the code later without realizing it. Now it's fixed. The turning is also fixed to make you think it's the protagonist who's controlling the riding.
The houses are free assets lol I would work more on the scenes when I finish the game. Again, the garage can only be entered inside the house, and all doors outside was intentionally blocked. I set it to show the door is "blocked" instead of "locked" to prompt you you can't enter.
Making something different was the thing I planned but couldn't spare time doing it, right now I'm just focusing to get this game done haha.
Glad you liked my game optimization! Spent some time on that. All the best on your game!
