I'm not very far in yet, but:
Dialog - I may not be the best judge, but it's not bad at all. You get lots of options to choose from, and the top one is almost always the "get through the conversation as quick as possible" one. The game also gives you lots of opportunities to say hurtful things to Amy.
Gameplay - Of whatever complaints I have of the game, this is the most valid. The negative status effects you can use on your enemies are things like "Weakened," "Vulnerable," "Distracted," "Sluggish," and so on. It's a little hard to remember what all these effects do, but I guess it should be expected of me to remember them in a game like this. However, several characters' special attacks are devoted solely to administering these status effects, and the game doesn't display what these attacks do when selecting them during a battle. This information is easily available from the menu when not in a battle, so I guess that's more stuff you have to remember or, God forbid, write down.
The music that plays during fights is okay, but some of the overworld music is just unacceptably bad. It's so bad, I'd considered it to be attributed to the fact that you need to patch the game to get it to run on an R4, and that was affecting things in-game. If you just load the rom straight up, you'll get a "Can't read save file" message, and even after patching it, it's currently freezing on a white screen on startup. Dirty piracy aside, if the retail game has the same music as what I've heard, you'll be utterly disgusted with it upon entering the second area.
