Nice game, here are some things:
*Pros:
- It's different to other Tower-Defense games. (that's a good thing!)
- It has the same look as the original "Minecraft".
- It has the sound of the original "Minecraft".
*Cons:
- It's very repetitive.
-There are few type of diferent turrets.
-When activating the "Speed Up" button the sound is terrible. (At least, I can't stand it)
*Some ideas if you make another game:
-Add MORE turrets. (at least 1 or 2, man)
-Add a tutorial or more tips.
-Add a way to upgrade the shelter (IDK, like a door that breaks up after a few hits)
-When the waves attack, it should be of night. And when the attack is over, it should turn to daylight.
****************
All in all, nice game.
(I reached to wave 50 in the Island, then Herobrine appeared and killed me XD)
