In addition to CAM's response, I could write a strategy guide given my playtime with this game. If you're having trouble, here are a few tips:
- Collect ALL of your partners (the main four) before farming or gaining exp. They will all start at low levels, so it's best to gather them up immediately so they can all share it. They can all be found in the studio.
- You'll come across these blue fairy/sprites scattered amongst the studio and zones every now and then. When you speak to them, always ask them to upgrade your strength! Defense is not as good, health can be obtained another way.
- Farm and milk enemies as often as you can! It doesn't take very long (typically 5 minutes is enough) and it will ensure you're strong at all stages in the game.
- Cat Boots in the main shop at the start of the game gives you an extra turn! Costs 10k gold, works super well on characters with multi-hit moves like Bad Girl.
- There's a boss rush hidden somewhere in the game... if you're exploring each room, you'll find it. It's farmable and it drops a shit ton of "Extra Life" which you can use on a character to give them more maxHP.
- DON'T TALK TO THE CAT MORE THAN TWICE! OH DEAR GOD DON'T FALL FOR IT!!!
