Alpha ?
Far, far away
...seriously I would like to do this full-time but then who pays my bills
...and you cannot sit from the morning to late night in front of the PC...
My roadmap for the next months is
- adding Towed Array (starting this week)
- adding Narrowband Sonar
- adding TMA, read only
If then people want to help by testing/giving feedback, I simply release a develop snapshot...but this will not be anything in terms of a 'game'.
