Thanks for taking the time to play Eclipse War!
Controls seem to be the #1 problem people have been having, so that's going to be my #1 priority to change.
Sorry to hear that you encountered a technical issue. If you don't mind posting the contents of %USERPROFILE%\AppData\LocalLow\Kurikaeshi Studios\Eclipse War_ Fetters of the World Soul\Player.log (or Player-prev.log if you've booted the game after encountering the issue) I could look into the issue. If you do I would delete the first couple lines with filepath info.
