I'm afraid my computer badly crashed when I tried to run this. I can't be sure if it's an issue with my computer or with the game, but I had to stop playing after that. I may have an issue with my graphics card, but no other games crashed it like this one. The game was pretty good otherwise.
I loved the graphics & the mechanics were solid. I'm not sure if you lowered the difficulty before the final version, but I actually found it pretty forgiving! Your life bar is very long so I was able to make adjustments to my strategy each time I got hit. Only problem I had was the skeletons were kind of "camping" next to the edge of the platforms they were on, so you basically had to take a hit when you came across them. The stalactites were too easy to hit some parts too.
