now that's some semver I can respect.
Oh! I meant this https://semver.org/ :D. I liked the numbering scheme you picked :D.
Aaaah, yes! It was a must! 😉
Also, I'm going roughly by this scheme and am using a 4th digit for preview versions.
In this case, it's a preview of version 0.6.0 because the 2nd boss and the procedurally generated caves are not implemented yet - and Halloween required something of a special versioning 🎃
