Arkagis Revolution had French support, why isn't French supported in Arkagis Escape?
The French localization wasn't done in-house, so it had to be translated after all the text was mostly done. The translations currently available in the trial version were done in-house.
It's too easy to quit the game by accident, why didn't you include a yes/no prompt?
We didn't have time yet (as of time of trial version Rev.XW), the menu will ask you if you're sure in the final version.
