Great use of the theme and I appreciate the juicy particle effects. Dani would be proud of you lol. I have some feed back / comments for you:
1) It might be my monitor but the background jitter is significant compared to the player movement. It looks like the background is moving at some pixel per half frame and then it would catch up. It can be a bit jarring when I was trying to appreciate the background!
2) For the music, it felt like a touch of mission impossible and I dig it! It does get a bit repetitive in the sense with the strings are playing the same thing throughout the song. Maybe adding in the drum part a little sooner to spice things up a bit.
3) The pixel art vibe is great!! Love the minimal feel. Those overhead power lines though, add such character to the game!!
Amazing job man!!
