Kinda weird how every fifth episode in the chronology seems to be a surprisingly good release! I think episode #50 is Daedalian Opus, so we'll see how that one holds up.
While not as fondly remembered as its dense, dark, NES counterpart, SunSoft's portable tie-in to Tim Burton's semi-camp classic Batman movie holds up fairly well. Despite some awkward jump physics and the occasional instance of super-cheesy level design, Batman stands out as one of the better Game Boy releases we've seen to date here.
