You're wrong on one point
I don't think your medals stay zero points because it has some ripped characters, i think they stay 0 points because you use the same shooting minigames over and over again, you use the characters over and over again, and because the graphics are pretty bad. Try to do something different than the same type of game over 10 times. I found it pretty good that you switched to games like bieber metamorph (even if it was voice acting), but now you're doing these button games again. I like that you didn't made any ''jokes'', because they only fail anyway. Try to take less pictures from the internet, like the store and the beach, because the resolution is even worse than your self-made characters. Try to put some effort in good, not self-repeating backgrounds, and it will surely get a higher rating.
What I did like was how long it is. It isn't as short as some other games of these sorts. But because it's so long, maybe you can use continues, so I don't have to start all over again when I lose a battle or something. Because there, you don't have three lives.
Come up with some clever ideas for puzzles by yourself, and until then, continue voice acting.
