Here's my let's play of your game ojosama!
Overall I enjoyed it, very beautiful looking game, and the concept is solid! However, it had a few problems...
As you probably already know, the bugs really hurt the experience, Ony_br already touched on this, but there's also the fact it changes the schedule randomly on weekends.
Just my opinion, it would've been nice if you'd actually explore the dungeons on an actual map, it being just a boss rush was kinda grating in the end...
The controls were very slippery. It was quite the effort trying to input my name for example, I kept messing up inputting too many letters... And the other menus were kinda difficult to navigate for this reason also.
Also, as for the fonts, they weren't working for me, and I don't know how to install them... Maybe a more thorough explanation in the readme, and a prompt in-game to check the readme would be good...
Otherwise I had fun! Good job!
