This has a nice retro "dungeon" vibe to it, the chosen sounds and arrangement fit the mood really well. I would have liked to hear some melody in addition to the arpeggiated chords, and I think that the drums in the second half have too much variation, which felt a bit out of place to me. Just repeating the pattern from 1:04 to 1:10 (maybe with some very minor modifications) would work better in my opinion.
