I want to add more enemies and improve the variety of the cave generation. I also want to improve the controls and combat, with more possible upgrades to find to make it more interesting. Instead of the game starting over when you find the exit, I want it to generate a new cave with harder difficulty (but you keep your items and upgrades from the previous cave). Basically I want the difficulty to increase as you go deeper. And perhaps some boss fights which can be encountered at certain depths, with a final boss if you make it deep enough.
