I'm actually trying to at least write some japanese with the help of a dictionary. But it seems I'm still pretty far away:)
Last week I was sent to the hospital due to food poisoning. Right now I'm almost recovered and hopefully will get back to work by the end of the week.
There is no need to report the demo's bug at this moment since about 80% of the .spt script will go through a revamp in order to introduce a new control system. This is designed to let players control the unit in a way totally different from controlling a plane after the unit transformed to a robot.
A new demo will be released around the start of November.
