If you want to keep it fully text-based, you can stick to Control-nodes (everything with a green icon). The LineEdit-node will allow the player to enter text-based commands, that you can process in a callback connected to it’s text_entered-signal. Restricting the input length is easily done by setting its max_length-property in the inspector. If you want to restrict which characters you consider as valid inputs, you’ll need to code this yourself by hooking up a callback to the text_changed-signal as well. The Label-node will probably be enough for displaying text. You’ll likely want to add the Labels as children of a VBoxContainer and wrap that up in a ScrollContainer though. If you want to he clickable text, you can use a Button with the flat-property set to true.
