Say whaaaat; I've been on Newgrounds for years and I had no idea Pixel Day was a thing! I have a huge soft spot in my heart when it comes to chiptune, so you can bet your sweet ass that I'll be making something for this.
Side note; here's all the other Retro Chiptunes I've made over the course of many years:
Mellow-Dee (feat. in Disposabot)
The Final Boss (feat. in Lava Bird)
