- There is no requirement to travel in a linear fashion in Castling's heart. You can go wherever you wish, and also revisit areas you've already been to as many times as you want. You will be able to pick up and move things, though some items will not be possible to move through areas. In example, there are some areas that will stay locked unless you move an item or bring something with you, etc. Some places will attempt to kill you, and in others Castling will treat you as an intruder and possibly chase you out unless you convince him otherwise.

- There will be one or two puzzles here and there, but it's more likely you will need to nudge resident Lucciolas to perhaps step out of their currently safe places/help them solve a situation or similar to progress. You will not be able to access the vital parts of the heart unless some requirements are met, however, there is a minimum and maximum amount of things you can change. What you change and how many things you change is up to you.

- There will be potential dangers everywhere besides the Hub, and you will feel as if you are being watched in pretty much every room. (There's only one exception to this.)

- Generally, every Castling you come upon will be very hesitant to have you around, but to what degree will vary. Do execute caution.

- TRY TO KEEP AN INVENTORY. I will do my best to keep up with what you move around, but it'd be very helpful if you helped haha ♥
