Great writing, hampered by the limitations of beepbox's mixing -- at 1:27 the reverb is causing a lot of resonance in the low mids that I would personally clean up
Would have been a BOP in the old arcade days!
The problem of reverb and resonance repeats throughout with low-tuned parts, and it is also hard to make out percussion, particularly kick.
3:03's busy bass occasionally is having trouble cutting through due to near notes in the low register.
By 4:30, the track feels quite long, with empty arrangement here. I might have saved some of these ideas for another song, but the outro is good, using a familiar motif.
Overall, great work and a showcase of composition skill using minimal tools!
6.7/10 comp score, 4/5 NG score for preference
