Add Aeris part entrance

Aeris part was originally intended to be placed in the DLC content. However, the content of the Zack part is not attractive enough, and the promotion time is not enough. So the Aeris part will be produced earlier. Please look forward to it!

I hadn't thought of a third-party publisher before, but if there is a good publisher, we can share the risk and achieve a win-win situation.
That said, the publisher's intentions are currently unknown and the possibility of cooperation is low. I am still waiting for a clear intention to cooperate.
Development is going as smoothly as ever, and the ideas keep coming, getting better every day.
If no collaboration is reached, the EA version will be released on 2021-6-19.
If a partnership is launched, it will be decided in consultation with the publisher.
Please be assured that the main development work of the game has been completed and the game is getting more and more full of content.
