Great start. However, is there a functionality available as of yet to sell/remove the items as to replace them with better items? If so then I would advise making such a functionality more visible to the players.

Be careful though. At first I was kinda annoyed by the game not allowing to sell a slot. But then I realize that this is meant to be speed run, with limited slot that the player need to think since the start of the game.
So depending on how you meant this game to be, that feature could be a detriment to the fun.
