This makes me so excited to play on Critical! I never really got the chance, so I'm really hyped! xDI did it.
I got all the Trophies in 0.2.
Those of you looking for a challenge, Critical Mode doesn't disappoint.
Another thing I noticed, is that Heartless give less EXP on this mode.
Overall the trip to 100% challenges (which will net you all Trophies) is pretty easygoing. You have to grind to LV80 though, which is lame. The toughest part is EASILY Critical.
Total playtime: ~14 hours over 3 save files not counting the hours I didn't save because they were just failed boss attempts on Critical ;_;
