Interesting progression. Sounds eerily familiar.
I feel like your lead should probably be taken down just a bit so as not to lay on top of the rest of the track.
Since this is lo-fi videogame, I can't really comment on sound quality a lot, but unlike Kwing, I do like your writing. With a little more structure, perhaps some more structure, this would feel more complete, vibrant. The main problem, the bassline stays roughly the same throughout, and that's where your lack of progression is coming from. Not to mention, percussion feels looped throughout.
Otherwise, not bad. I enjoyed the piece. If revisited with more attention to structure and progression -- there are lots of great song-writing tutorials on YouTube for this -- I see the potential for a great videogame soundtrack. Seriously, great lead writing. :)
