The game is at Bedrock bottom, here's how you add love to the game:

With chemistry!
Expand on the brewing portion and let light have a more vital role.
Implement Notch's first idea of torches going out in dark. because you introduced laterns. (adds an extra dimension) 
Invite the team of optifine to improve the basics of your code. 
Also if you have the Nether, why not an Aether (Sad netherlands noises) 

Aetherway! (Pun Intended)

Choose a platform! 
Bedrock or Java
Connect players. Java version had its purpose but you created a more stable version. 
Kill your darlings or improve them

Good luck!
