Both Unoriginal AND Original
I kind of found this game to be a bit unoriginal because it is a Mario parody game (then again, so are MOST other games on this site, so I probably shouldn't argue =P). But what made this game also original is that it also includes a Tetris-style feature; never expected THAT, my friend! ;D
Seriously, though: the whole "Tetris theme" included in this game really made this worth playing! You should be very proud of yourself! =D
The reason why I gave you this a 9/10, however, is that you should really include instructions on how to play the game (mainly moving the character; I DID see that Yoshi instructed us to press Space to switch between games). Yes, I KNOW that the instructions involving moving the character is mentioned in the description of the game; but what if this game was posted on a DIFFERENT game site (BESIDES Newgrounds, I mean)? =\
And before i forget, ignore the guy below me (27DeMayo). ;D
Good job with this game! =)
