Pros:

- Looks like Minecraft.
- Nice amount of supplies.
- Confined, but so many areas that it doesn't necessarily make it harder.

Cons:

- No creepers

Conclusion:

Liking it a lot. Stick a custom skybox on it, when you can, too!

Pros:

- Feels/looks like Minecraft.
- Nice flow to it.
- Bill! ;_;

Cons:

- No creepers! Well, that might be a pro...

Conclusion:

It will be 100 once you add a creeper, and there's a contest for boss monsters so you should do that!
