Unfortunately the difficulty has such a large impact on the enjoyability of the level that I cannot pass the fact that it's extremely hard. I'm not the best mine jumper by far, but dying at every second jump was quite bad. The map lost its fun quickly, and even more so because I've seen how much is left (three quarters almost). I think this should be either toned down or an easier version released.
On the positive side, the level is very precisely made, there is full use of almost every block, so it finally got a 3.5.

2.0 for fun factor, 4.0 for tileset.

too hard, eh?

I got that far
