TWEWY is FREAKING AWESOME! I've had my copy since the August, and I still obsessively play it. The story is fascinating, filled with twists, the characters evolve, so many things tie back into eacother, it's got a VERY interesting way to level up and increase your stats, you really can't neglect details if you want to finish 100% and then you can go back and replay levels whenever you want once you beat the game.
Okay, so you level up by beating baddies BUT
1) by wearing certain clothes you can increase stats. By buying clothing you increase friendship levels with stores, and they give you "how to use clothes" more... does that make sense?
2) by buying food you can increase levels. Like increasing attack, defense, bravery (so you can use different clothes)
3)you can fight at any level you've reached. So, I'm at 81 or something. I can fight at level one (and increase my drop rate as high as I can) but I lose alot of my possible hp. Fighting at my highest does the reverse.
and... that's not everything.
