The style is the best part of the game... I love the pixel aesthetic, i would love to know how you did this, the game has very good mecanics, but you get bored of it and there is no real objective or anything to complete, good job tho
in Unity i just made a low res render texture and set the output of the camera to that. then i make a big UI image and set that to the render texture. if i then want to add UI i just make it in world space so it gets rendered to the texture aswell
