attempt to index a nil value (field 'velocity')

[arch-linux]

I understand that your project's purpose is not to serve as a Playdate project example.

As a newcomer to the Playdate environment, I attempted to utilize some of your codebase to help understand LDtk and also tried cloning the project. Both approaches resulted in the same error:

Update error: code/player.lua:59: attempt to index a nil value (field 'velocity')
stack traceback:
	code/player.lua:59: in field 'update'
	code/game.lua:76: in field 'update'
	main.lua:40: in function <main.lua:39>
01:12:20: Update failed, simulator paused.
