Thank you! I'm still quite new to Lua but I'll give it a try. I'm planning a few scenes where the character walks down a long street. Like in Thimbleweed park. There the control is also solved this way and I find it quite intuitive.
I have that game, but I haven't gotten round to playing it yet - probably never will - so I've no idea how intuitive it is or why they would use that sort of system, but ok sure, I'll just have to take your word for it.

Anyway, if you get stuck with something just post on here, or alternatively join our discord server @
