Okay so I'm kinda just taking myself to be a tester here, so I've played about 10 minutes and found it casually enjoyable :) However I've found a few minor errors that could be fixed if you made an updated version.
1. In the starting text, you put "get to the answers" instead of "to get the answers"
2. (as seen in screenshot) the "Special BGM" shares the desc' of the previously viewed shop item.
