I haven't played much so take what i say with a grain a salt
1. I could't get hooked to the game it's overwhelming to much is introduced in a bad way. Instead of showing me a book at every new screen, tell me how and why to do something then let me do it then tell me how and why to do next thing . Baby steps.
2. Make it clear how to enter/exit the slime info page, or perhaps it requires redesigning it feels very off to the side (disconnected), for all the info that you want the player to read and look at.
3. It's still is an early demo so i understand lore will come in time but making a connection between the slime designs and there abilities and all is important and needed cause right now it's disconnected
