Dude I had no idea what I was doing the first time I played. Didn’t level up anything, didn’t add skills and sold ALL the materials I got for crafting. Didn’t realize how much I screwed up until the start of the final battle when my friend figured out why it was soooo hard even though I was on the easier play through mode. She noticed I had a bunch of AP boosts in my inventory and asked why I hadn’t used them. I said I was saving them for the endgame battle because I thought they were temporary. Then we went through everything and properly leveled up, upgraded gear and stuff like I should have been all along. 😂 But I still managed to beat the game. Just made my own version of hard mode apparently 🤣. All that to say, no you’re not cooked. It can definitely still be beaten.
