Hi, so in the earlier builds, I've created a short description about stats for the game introduction. But since I thought that people can figure out each stat, I removed it. Thanks for the suggestion, I think I'll put it back again. Here's a short info about stats. ATK: Affects Atk-based moves; SP.ATK: Affects Sp.Atk-based moves; VIT: You gain 4HP and affects Vit-based moves, SPD: Affects your accuracy/evasion, LUCK: Affects crit and status effect chance (only crit for now).
Defend is very useful in the second area where enemies can inflict several negative status effects to you and you need time to gain your AP or just tank some damages before you can recover. Also, some enemies will have a special attack cue text, which makes defending very crucial.
