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 !
