i've also beat the game quite a few times (along with dome of my friends) but i was wondering if you could tell us how many secret characters there are? i found Mario and i remember finding a girl character, but have never been able to find her again, or maybe i was just hallucinating, its happened before. if you do end up finishing the game could you please move the part where the secret characters are? it bugs me how Mario is kind of in the middle left of the bottom of the screen, it makes me think that there is a lot more hidden characters, or that i mist a bunch in the previous levels.
thanks for making a great game! i'll be looking forward for the full version if it ever comes out!
