tick tock: what a bright, fun track! It's important, in competitions like this, to rely on the theme in order to stand out. The sounds of people counting, as well as the metronome, are smart ways to tie in that theme and win some extra creativity points ;)
I'm super impressed by the way you keep this track sounding fresh. Lots of fun melodies and constant changes in the beat. This track belongs right up there with other sonic tracks.
gameover: love the chillhop vibe here! Another smart way to establish unity between tracks, especially those which have such contrasting vibes, is to borrow elements like chord progressions and melodies-- which you do beautifully here. It almost feels like a variation of the previous track. The oscillating pitch bend is a hair too wide for me, and it just confuses my ear instead of sounding like an old-timey piece of machinery. Also, the bass drum is really forward in the mix.
In all, these two short tracks are bursting with personality and energy, and sound very unified despite their contrasting vibes. Great work, and keep writing!
