Hey, i have played this game!
It's among the games that are hard even with extensive use of save state...
The version i played was special though... it was a beta version that i had found on a random cd!
And that version suffered from a major bug that prevented it from being completed!
It was a funny bug! there was a cutscene before start of one of levels where main character was supposed to jump two times and land in a cart... however, it used wrong button for doing so, causing main character to attack two times instead of jumping! resulting him to being stuck in there and we couldn't do anything at all to recover it!
But the persistent me didn't lose the hope, and i created a special cheat code for it which repositioned the main character and voila! the game continued!
The game itself is not that great... but challenging that bug turned this game into one of most memorable games for me!
Note: The version available here is not infected by that bug.
