Not a bad collab
It's been awhile since I've seen a collab game, so this was quite refereshing. What I didn't like about it was how it wasn't that well detailed. At least you guys managed to create some fairly different levels to interact with. I think the weirdest part about this was probably how I was foolish enough to go with the "Hard" mode at first, which was a disaster. I also liked how you could play Pong while you waited for the game to load. It's fairly nice all around.
Now, it could have more going on but a collab like this doesn't need that. If a game was really that complicated, it would have made a submission in itself. It's interesting to hear how things worked out for this. I liked the wide variety of songs being used. Seeing as how it's numerous games, it makes sense there would be a lot of music.
