Thanks for trying the game!!
I tried in fedora and it looks like `guile` package installs version 2.0 which I haven't tested.
Please install 3.0 instead with `dnf install guile30` and either:
A. Link `guile` to `guile3.0` so the default version is 3.0
B. change `./run.sh` script to call `guile3.0` instead of `guile`
I will try to upload a new version changing the `run.sh` script to detect this issues.
