Thank you for your comment! We're glad the characters appeal to you and it's always nice to know that our little cinnamon roll has fans!
We will be reworking the thoughts vs. speech with Rei so that it will be more easily understood. There won't be as many spoken lines as a result, but it will be more easily understood from a player perspective. This will be touched on more in a future update!
We may make an overall tutorial available once the player starts the game, just as a brief introduction to the mechanics. Again, touched on more in a future update!
Thank you for the critiques and the in-depth comment! It is very much appreciated and we hope you will enjoy the full game when it is released!
