I found this to be better than the first game, if only because it was a lot zanier. It really helps that the tone changes so quickly. First, we get to the part with the darkness and nothing happens and then we get this fast paced mine game! That is easily the hardest because you move too slowly. When I press the up button to get up, I don't have enough time to press it again as I don't hit the ground again! Anyway, the music (wherever it was) was extremely fitting as well.
For the first level, try to completley avoid the part of the bridge that will fall down. In the next part of the level, try to just jump at the beginning so the spikes won't hit you on the way down. Oh, and be sure to catch those buttons. It can be so annoying when your reaction time isn't good enough. Thank you for this awesome game!
