Hey duo, I'm glad they're helping!
There are actually peek and poke commands in TIC-80...I'm messing around with them right now and hoping to post a tutorial on it soon. btw...love your avatar...I too didn't have a bandit mask and had to modify a tube sock :D
And there's more TUTORIALS out!
Using mset() and mget() Functions
Making Realtime Minimaps
Random Point Level Generator
GBF Pathfinding
again, if you check the tutorial page frequently you may have already seen these :)
