It took me a few days to find out what was causing the bugs. I'll summarise them below:

1. Movement/Input bug
   1. So apparently, WebGL doesn't allow Unity's input system component (Player Input) to be on multiple objects. 
2. Bug with the shop:
   1. I fixed the block check so it actually places blocks. 

Known Unfixed bugs:

1. Clicking "exit" when the game ends doesn't reset the scene properly so the game breaks. Reloading the page is the only way to play a new game.
