Hello! So sorry for the late reply.
I have received many many requests for this game to be translated into Chinese. When I do multiple language support (which is sadly a long way off), Chinese is the top language on my list.
Multiplayer could be interesting, but the core of the game is about to change once again, so multiplayer is also a long way off.
I just played through the game with a friend and I totally understand what you mean when you say the beginning of the game is hard. It very much is and I'm sorry I haven't balanced it quite well. However I have come up with solutions to directly address this issue for future updates.
More music and sound effects would be great, and I would love to polish up the game some more with a full soundtrack. I will do my best to add polish along the journey to completing the game.
More realms? While I do not think that more realms is the solution to a short gameplay experience, I have ideas to make the game more engaging in the long term. The final boss is a terrible design way of bringing the player back because there is literally nothing after you beat the boss.
Landing the game on steam? I have plans to publish this game, I am not quite sure on the timing.
I am very glad you enjoyed this game. Cheers!
