The good news is you didn't really miss any content! The game will normally be much slower paced once I'm able to add more stuff, but with time constraints I tried to make up for the lack of depth by increasing the difficulty but it appears I may have overdone it lol
I tried to set the difficulty where I could beat it most times while it still being a decent challenge and kind of forgot to account for that
a.) I know literally how everything works
b.) There are very little QoL features I've been able to implement to help players understand mechanics in the game so every player is going to miss a few things here and there making it more difficult as well. The UI is also a mess, I wouldn't be surprised if people would try the game and not realize you can sell/combine items.
I appreciate the feedback though, thank you! :D
