This project scales your game like "Hyper Light Drifter" It's pixel perfect at interger values and will be ok (atleast better than the default) at non interger values. No more artifacts or distorted pixels! and it auto detects your aspect ratio! What a catch!

rescale the window to see the scaling in action
This is also an UPSCALER, so going below the target size is not reccomended but since its pixel art I doubt anyone has a screen smaller than 360x270
Sorry for not a more detailed view but im swamped at the time!
