It definitely entertained me...
At least for a while. After that while of time elapsed I found certain levels tricky enough to try my patience a bit (specifically the dark/ghost levels). Perhaps that's just me and my own personal patience level showing through. Overall the game was pretty well done, the music was decent enough and even though my patience was tried for a bit there, the game kept my interest long enough for me to want to beat it and not give up like I do with other games that aren't as interesting but are just as tough, if not more.
