I thought this was great and definitely fit the vibe you described. I loved that low synth below that higher main melody, it put a menacing feeling underneath the nostalgic tone you set with the bell-like melody. I loved the ticking clock in there as well for percussion, and tying into the theme. My only criticism, and I think it's because you mentioned running out of time, is that it doesn't quite build enough for me at the end, I think it could get slightly bigger. That's a small subjective thing though, Nice job!
