Gorgeous assets! I just bought the bundle that includes this. So excited to make a game with them!
I had a few questions though if that was okay. Forgive me for being such an amateur! I've been messing with the tiles in Game Maker Studio 2 and I just can't seem to get it to look like your examples.
What is the background black that you're using that makes it look so amazingly retro?
What size room/viewport would you recommend for the best look?
Thanks so much!
