The inventory and resource management is really cool and adds a layer of complexity and thought to the game. I find your UI to be very nice by tracking health, score, ammo, and more. The UI for inventory management is very clear and nicely placed. The background and spikes match together well for the cave theme. One critique is to make the visuals extremely clear like when you are shooting the tiny mobs and the bullet visually is difficult to see and almost seems like you may miss. The overall mechanics and interactions are nice.
