2D Sandbox, Base Building Game! Thread

DISCLAIMER! I HOPE I AM NOT BREAKING ANY RULES, IF SO, PLEASE RESPOND DO THIS THREAD TO TELL ME WHAT TO FIX! Thanks!

Hey guys, Mystic here! I am currently developing a 2D adventure sandbox game, with inspiration from Terraria, Starbound, and Classic Base Defense games. I have just started on the 4th of January, setting daily goals. So far I have sprited the main character, and I am currently spriting the first enemy. I have come to this thread for ideas for the game. So, let's start with talking about my Minimum Viable Product!
Minimum Viable Product
Character can move/jump/attack
Enemy can attack me
I can die
I can destroy blocks
I can place blocks

Now let's move on to the aesthetics!

This is the basic screenshots of the first version of the game.

Story
The basis around the story is that, well, you make your own! Whether you're a scientist with an experience gone wrong, or a mage, who teleported through a portal! You get to choose your story!
