Very painless. And for this series, that makes it above average in my eyes. Nothing to really praise or anything but the hour I took to beat this game left me feeling more positive than I usually am after playing a Mega Man game not gonna lie. It's a very easy game but to be fair NES MM2 is also one of the easier games in the series to begin with. I can definitely see my 7 year old self getting pretty into this one if I played it back in the day. If you love hearing the Gameboy squeal in agony you'll love the soundtrack. Lucky for this game, I'm a 100 gecs fan and I'm into that sort of thing. (But seriously the compositions are great, the soundfont choice is baffling, even if I do get a kick out of it anyway)

Overall a nice palette cleanser if you're doing a bit of a Mega Man marathon. For a series that at the time was getting 2-3 games a year you'd think the Gameboy version would be a LOT worse. I suppose it helps that the games its based on are very simple to begin with.
