Hold up there, not quite. Our Standards say, "Sound effects alone are not considered music, and submissions primarily consisting of them will not be accepted." What that rule mainly speaks against is constructing an wholly original music piece out of in-game sound effects or placing SFX & voice clips over an instrumental not based on game music, neither of which we count as VGM arrangement. There's nothing in this concept incompatible with OCR, including extended audio intros, just so that's clear to Angélique, the judges, and anyone else interested in the standards & guidelines.
As far as how I'd look at the source tunes being dominant, I'd just look for the source tunes to be referenced during at least 50% of the musical portion of the track, in this case starting at :49.
The gimmick is awesome, including the pseudo-voice acting with the song construction steps, which is supposed to sound robotic. I agreed somewhat with prophetik in that the overall development here feels limited. More could be done to make the steps sound like the track's evolving more substantially over time, but I also think there's enough done in terms of gradually adding parts here that can be taken in conjunction with the premise here.
However, you still have to have reasonably solid production, even if the premise is reviewing the building blocks of a song. I'd just say the samples mostly sound super fake, whether it's the pizz strings, piano, claps, or mallet percussion. Stuff shouldn't sound so exposed and unrealistic. The bassline brought in at 2:25 was off-key, but seemingly wasn't a problem once it switched to arranging Bomberman Hero "Redial" at 2:57. As this point, the groove is fleshed out some more, but very stilted with textures that are thin and not fully filled out. It wasn't until the string lead at 4:33 from :20 of Ape Escape "Oceana" that it felt like the song finally had some more body to it, but it was still hamstrung by all of the other previously mentioned issues, so I can't say that things actually gelled.
Until the instrumentation is humanized and given more body/realism, Angélique, this is a fun concept without the complimentary production execution. Cool stuff though so far, Angélique. Consider seeing what more you can do with it in terms of beefing up the production quality.
