Awesome entry!
The only thing that bothered me was the “go” SFX which was in some way not playing well with the music. But it’s a nitpick for the great game! :)
you've got such an awesome ear to notice this! and you're absolutely right that they're not in the same key, it creates a dissonance when it plays. I had never noticed it before you mention it, most likely because during all the playthroughs I ended up turning the music off as it had become very repetitive. I'll fix this, thank you!!
