There are a total of six levels. The first five levels are pretty hard, but definitely doable. The sixth level however is extremely difficult. It was actually designed to be borderline impossible so don't feel too bad if you aren't able to do it. Oh yea, did I forget to mention you're at half a heart the entire time? Anyways, that's basically it. If you're able to beat the first five levels then you are a pro minecrafter, but if you beat the sixth level then you're an ultimate minecrafter. That's about it, good luck! Also remember to take breaks from time to time.

Hint for level 6 in case you're lost: You need to gather six keys to open a door in the back, and there's a second yellow key hidden somewhere in the cave. Good luck!
