I really like the look of this game; well done with the pixel art! Personally, when running this game, I was getting really low FPS and it lagged a lot (inputs felt unresponsive), which I'm guessing is related to pathfinding that could be optimized, based on the game description. It made the game really hard to play; I ended up just heading left and found a hole that I jumped in, and the credits showed up. I can't say much about combat or the use of the flying drone because of that, but the idea is pretty cool. It feels like you could turn this into a Metroidvania style game where you explore the caverns.
Overall, well done on submitting this entry for your second game jam! Would love to see you add more to it and optimize even further.
