Game Vortex reports:
''As far as presentation goes, Summon Night: Twin Age looks and sounds great. Although some of the characters suffer from a twinge of "generic anime", they are fairly well detailed and really stand out, especially on the DS's screens. The same can be said for enemies; there's a lot of palette-swapping going on throughout each level, but a new crop manages to work its way into the mix just when the old set outstays its welcome.
Story sequences are told via giant character portraits that slide in and out depending on who is talking. While some games might try to get by with one or two portraits, Twin Age features several that hit a full range of emotions. These are further accompanied by short bursts of voicework. There isn't enough to really say "yay" or "nay" on the quality, but like the multiple portraits, it lends enough kick to add a little emotion to otherwise plain text.
The soundtrack is great, though very few of the tracks really stand out. However, long-time readers will probably remember that one of the few credos around here is that the best soundtrack is one you really don't know is there, placing Twin Age in good company.''
