@drjeats@octodon.social ah, thanks for the suggestions! I've only had one shot at GameMaker and it was when I was still getting very easily frustrated with things that didn't make immediate sense. I'll start giving the unfamiliar things a look-see.
I admit most of the fun I got from Unity was with playing around with 3D geometry in code. I'm less of a computer programmer and more of a science and math geek who got into computers after the fact. Unity gave me a chance to do some trig again XD
