Protoman Battle Network 1 is inspired off the battle network/ network transmission games. This is a 425 screen level (which doesn't feel near that long I think) as you play it. The layout is condensed into 3 major zones (Den area 1/2/3) and it contains a fun shop to help you on your journey.

If you have access to the level discussion channel on discord, the full post has NSF replacements as well as a very detailed in-game map.

My post will explain it if you're interested! I hope you'll consider giving it a try and have fun with it. Thank you 🙂
My upload run took me around 1 hour 20 to complete
