@SimΞon I find it weird that INC is slower than simple addition.
I know about the fact that it's interpreted. There is however a cost in calling functions, and I was mostly trying to figure out how costly it is to call something dynamically like this. I want to create some more advanced program flows, and just DEFs are not enough :3
Search for PetitProfessor3D on YouTube, he has a lot of tutorials on the basics of this language. Also make sure to read the manual of this game.
And don't get discouraged. At first it might seem too hard, but you'll get the hang of it and make some amazing stuff ;)
