Hello. We've already fixed two things.
1. There was a rare case that the game changed the difficulty level. This shouldn't be happening anymore.
2. Previously, if you had played demo you probably would have had an issue while trying to play the full version. It often didn't want to start at all or the vendors were broken (pun not intended). The problem is gone.
Now we're working on the English translation (proofreading), and eliminating the crossbar (the game can cope without it).
The release date isn't confirmed, but that's the deadline we set ourselves.
