Definitely a good track, simple but effective. I think some more melodic development would have been nice (solos, lead lines, etc.), but the progression is catchy and that central rhythm in your 8-bit synth does a surprisingly good job carrying the song forwards-- even if I also think it too could use some variation in rhythm and progression.
That's my main criticism here, the song isn't varied enough. Skipping around, it's basically just one big long section. Some EQ work on the chords, and general effect work/ mixing could also be good, but that's far from your main concern here (at least, IMO).
