Everything was more fun on Normal, now that I knew I could kill the lightbulb in one charge cycle. That said, I hit a huge wall after the checkpoint in Wily Fortress 2, somewhat ironically before another lightbulb fight (who posed no problem), and it killed my interest in playing for a few days. After finally clearing that hurdle (dozens of attempts later...), I found the rest of the game quite fine. I did abuse E-tanks to power through some bosses, though. And I only just now learned how to deal with Pump Man in the Stage 4 teleporter area.
