Sorry about the PTSD, but…
I have never met anyone that could beat this level. It’s like it was made to sell the Game Genie.
Child me could beat it after hours of repeated attempts and running out of continues.
Adult me went back after a decade. The muscle memory was still there and I beat it on the first try. I probably got about an 80% success rate on first attempts now. But level 4 and beyond I’m terrible.
I watch a streamer who mastered speed running dozens of NES games. He says Battletoads was the hardest game to learn. Just getting through the game, not even pushing for a fast time, was extremely challenging. Much harder than TMNT 1 or Ninja Gaiden.
I need to find an emulated version of this. Mine was faulty and always glitches as soon as you finished this stage so I never got to see neyond it for more than a few seconds. I’ve always wondered what was there!
