Thanks for the feedback!
Honestly, I did it the hard way most of the time…I made a lot of the rooms in a very plain design and then started slowly adding detail to different sections but literally one tile at a time.
For the title card I did a draft in Paint and then used a solution to import it (Search the Playdate dev forums for the latest solution to that) and then cleaned it all up.
But mostly it just took a while of doodling around in the editor. One tip, I didn’t realise the tile picker tool was available (like a colour dropper icon) which would have made a lot of the process much faster!)
