Doing a quick check on the samples, if you submit as is you'd likely be alright on that front. Aside from the orchestra hits (which sound sampled from the MMX library), most of the samples + instruments used here are just different waveforms and FM synths, which can't reasonably be misconstrued as Square-Enix SFX (they can't reasonably claim ownership on FM synths and basic waveforms, after all).
Rozo is correct that all artists submitting need to be careful with the samples in that regard, but I think this is alright here in that regard. Neat arrangement!
Harry Potter and the Chamber of Secrets for the gameboy color. That was a really oddly balanced RPG, with the possibility of getting through most of the game rather easily, then suddenly hitting a boss that was absurdly harder than the other bosses up to that point.
Then you get to the final area, and you had better hope you were strong enough, or the random encounters would be too much for you, you would run out of items really quickly, and you would have to grind REALLY slowly to be able to beat the game. Worst part was once you got to the final area there was no going back at all, so you couldn't grind on slightly easier enemies. Then the last battle was disproportionately more difficult than every battle before it.
You ever play Jet Moto 2?
The CPU are all playbacks of the best players they could find. As such, most of the CPU opponents have a near-perfect run.
Screw up even once and you're almost guaranteed to come in last.
Arguably one of the best, forgotten soundtracks in video games, though.
