I did used my idea on HowTo: dynamic grid tutorial video for the tiles (grass, and floor). Here is the link if you ever want it https://youtu.be/ABEwdnne9AI (It's for Unity C# only by the way)
Be sure to subscribe to my channel and I'll try to make more howto video tutorials whenever I want.
Also, the source code for this "37 hours in a room" game is messy cause I rushed it. I didn't even try to use some inheritance or whatsoever complex design patterns.
