Success! All of the main systems seem to be validated and calibrated, and so it's just a matter of getting the animations / cutscenes put in and the boss tested.
Whilst I won't promise this time (as a professional coder knows you'll run into a wall of bugs if you make promises), I am trying hard to get this out by the end of this month. Finally... the path for 0.02's release is looking clear and I can see the light at the end of the tunnel!
