I always liked tunnel effects and I wanted to see if I could make one in PICO-8 with a simple method of drawing circles. I think it turned out pretty well. There is the issue of gaps between circles, but this does allow you to see parts of the tunnel further in the distance which I find interesting. I also gained a bit of intuition about shaping behavior with sin/cos and square root functions.
I also decided to try out the music capabilities of PICO-8 for the first time. I was mostly inspired by a track from the game No Time to Explain. I don't remember which one, I have just had parts of the melody floating around in my head for years.



Very cool music and visuals! I'm really impressed with the sounds you got out of that lead instrument - it has a haunting, almost voice-like tone at those low pitches, and you use the vibrato and portamento so expressively!



Thank you! I really appreciate it. I was going for an interplay between sort of dark and sort of adventurous. I had Castlevania and Starfox in my head.



Looks cool
That looks like it could be a cool tunnel-3d space shooter with a bit of re-work :)
