This used to be one of my favourite Mega Drive games, not least because of the tiny Sunsoft box it came in, but over the years time has not been so kind and it isn’t as good as I remember it being.
Part of the problem I’ll say upfront: I totally forgot, until the final level where I did it by accident, that it was possible to double-jump. This afforded Batman a bit more height, a bit more distance, and the ability to damage baddies on contact as he somersaults into them. The other problems were things that have worn me down in more recent years, like bosses that require you to repeat the same action, in exactly the same way, over and over again and leaps of faith. Or grapples of faith, on some of the levels – there’s no way of knowing if you’ll grapple up into a baddie or some spikes until it’s too late. And there’s a SuckySuck(TM) bit, only made worse by the repetitive boss fights. The batmobile and batwing levels should have broken up the mostly dull platforming sections, but the former was way too long and easy, and the latter way too hard and frustrating.
I suppose not all games I loved when I can younger can still stand up these days, unfortunately.
