If you did this with really verbose variables and comments as a "real cart" (but with no more fidelity/complexity), it might be a good instructive cart for beginning coders...
Ooh.. that's a good idea Tom, thanks. I planned to do my usual code walkthrough post, but it didn't occur to me to potentially use this as something for beginners also (albeit with less "hacks" this one needed! 😉). I'll think on that idea more. 👍
Cool, yeah, because simple tile-by-tile movement games reduce complexity a lot. Like Dylan Bennett's Top Down Adventure Tutorial. Much simpler than a lot of games. Easy to explain. Anyway, much more involved than my TweetTweet games heh!
