It really reminds me of Spelunky. Just add a shop and more roguelike elements and you'll be golden. To be honest, I played way too much!

Spelunky was a bit of an inspiration behind it hehe! There is also a shop if you get far enough into the cave, you'll fall down into a little area where you have a choice of three items to purchase using the gems you get for killing enemies!
Also, we're totally planning on developing the game further and fleshing it out into a full roguelike experience, we had so much fun working on the game so it's super exciting to be continuing with it and adding more items, cave types and enemies!
