Yeap, it was pretty cool. But there are two things that annoy me: mummies and big magnets. Especially when they give both at the same time. I managed to get to the last level without cheating, and stopped at the place where you have a very small lift going up and down, and a timer that opens a magnet which attracts the ball. No idea how you have to get there in time... The maze later on was also extremely annoying with its teleporters (kinda reminds be of the Endless Spiral in Might and Magic 1 though). Why do those three buttons emit sound and no nothing? The platform jumping is also extremely fast, I never managed to do that, and that waterfall place later is extremely annoying because of spawning mummies! What the hell!
But talking about bugs, I managed to break the game in the part where your ball goes out of lava, is attracted by a huge magnet and a mummy chases you around. I unlocked my ball, but sent it back too far and it got attracted by the large magnet again, but this time small magnets did nothing. Had to restart to make it work.
