WOW!!! I used to play that game all the time!!!
I beat it with both the bad and right ending!!! It's pretty tricky to get the crystal to access level 100 because the map you find the crystal in is so packed... Plus, the crystal dissapears in like, three seconds!!! I also remamber those slimy dog things that fly (they pissed the hell out of me!!!) and how crazy and tough they were to beat when they turned white! Wow, this animation brought back great and frustrating memories! Thank you!
"5"!!!!
