I'm giving 4 out of 5 for creativity alone, but the game is not that entertaining. Perhaps if you incorporate some of the suggestions in here next time...
Although this game has a lot of glitches, you actually managed to do a great work! Why don't you adapt other PS1 classics, like WipeOut or, dare I say, Final Fantasy VII? :D
Good game with an interesting story. Too bad that you don't have to think and that, instead, you have to pixelhunt in search of the items. I spent 15 minutes searching for the last skull and had to watch the walkthrough to find it. Still great game!
Nice concept, not that original though. It would be interesting if there were actual phisics involved with the tetris. And could the screen move a taaaad faster please? :)
