ok i seem to have a basic grasp on it
pretty powerfull toy, I love how you just connect physics directly to the image object and stuff works. no tick or update loops. Feels a lot more intuitave compared to unitys 2D also.
lua is however missing a few things i am used to such as vectors and object orientated stuff (like if i want to make my own enemy class)
i found a vector class online. but i struggled to make it work, so i hardcoded some basic stuff
and it seems that by using lua tables you can replicate object orientated programming but it is not as convenient
