I think the checkpoint should look like a spawn brick with no arrow.
Keys- 4 different colored keys. If you use them on a brick that has the same color, it will fire OnKeyMatch. If it has a different color it will fire OnKeyMismatch. This is a "complete the objective" sort of key not a "personal ownership" sort.
This is gonna be awesome.It's good to see some more default add-ons to be released.
who said anything about defaults
They will be part of v18.
