Shameless plug: I'm working on a [Text GUI library](https://github.com/Hexworks/zircon) which has the option for isometric projection [like this](https://cdn.discordapp.com/attachments/205245036084985857/41...). It is completely decoupled from the backend (the simulation engine in your case) so if you are interested we can work together. I also work in Kotlin and I'm eager to put in some work to create a fun game. It also supports tilesets so you are not stuck with ASCII.
