Thanks a ton! I've been super anxious all day hoping the first review I get isn't "I softlocked here" or "The game didn't compress right and I can't play it", so seeing someone play through the most recent build to the end without any significant issues is a massive relief.
What level were you near the end? I was usually level 4 or 5 by the final boss when beta testing and it was a tiny lil bit of a challenge for me.
If you're talking about the song near the end, it's the only song where I didn't use the triangle wave as a bass, so that could be what made it grating. I should have balanced the audio a little better to compensate since the triangle wave is quieter than the square waves. The very last chord is also one of the only times I used an arpeggio for a chord instead of just two notes at the same time so I could use the other square wave for the bass. (The other was simulating the muted guitar chords in Theme6.) If you're talking the song when Reid appears in the world, that song deliberately used discordant tritones to really capture the shock of waking up in a NES game.
