Thank you very much for your message! It helps me better understand how others play the game. I aim to improve the points you mentioned.
News:
-When you first find yourself in the park, there is now a map tutorial.
-For the concert, there are now two hints to encourage you to go there.
-With Marceline, I've just released a small version in the demo; I've managed it better because there are quite a few evolutions.
-The name Ben has been replaced; it's the default non-dynamic name.
-Marceline's questionnaire has been improved.
-With the receptionist, indeed, you cannot evolve her a second time. I have removed this misleading option.
-Thank you for appreciating the little animations I made.
-As for the achievements, not all are available right away. I have set up a list that will grow. Currently, I think I'm halfway through Chapter 1, so there are plenty of achievements to unlock.
