Hi, we plan on making our game in LÖVE engine, and we already know a neat library that allows us to change the resolution of screen. Can we use it in our game? The file is push.lua

Yeah, there's no restriction on how your source is structured.

Hey draketrout, here's a library called sugarcoat which you can use with Castle and Love to make your game retro-inspired, if you're interested! https://github.com/TRASEVOL-DOG/sugarcoat

Castle will allow you to scale your 64x64 pixel game to full screen, if you want, using its dimensions API: https://castle.games/documentation/castle-file

Hopefully this is useful info. good luck with the jam !
