Thanks! I appreciate your feedback!
Clickable buttons make a lot of sense. I was on the fence about implementing that feature because I wasn't too sure how to go about it, but you convinced me to try! So far it's working out.
Ooh, I like that idea. Would definitely be too ambitious to add narrative elements at this point, unfortunately. My free time is a bit limited now that I'm working part-time, but I'm determined to submit this project.
If you haven't found the answer for clickable buttons yet, here's a snippet from my game - in Update() you want to check for the mouse click, then get the position of the mouse. Last line converts it to a tilemap position if you're using tilemaps.
if (Input.GetMouseButtonDown(0)) {
Vector3 clickWorldPosition = _mainCamera.ScreenToWorldPoint(Input.mousePosition);
Vector3Int clickCellPosition = _shipTilemap.WorldToCell(clickWorldPosition);
