To begin - absolutely love the asset pack.
Since you're asking for suggestions for things to add (In no particular order):
- Heian Period Villagers
- More Pixel Fonts in TTF format
- Larger elemental magic effects
- More FX in general
- A paper doll actor generator
- Humanoid Bosses (A large ninja or samurai or whathaveyou)
- A Tengu actor / monster
- A shrine / temple tileset
- Samurai cavalry actor / monster (Bow and/or spear and/or sword)
- (I'm aware this is massive) FFV style emote sprites
- Emote portraits
- Fancy period interior decor (Display walls, redwood furniture, decorated folded screens, etc)
- Different looks of samurai (ashigaru, ronin, etc)
- Ability Icons (Melee attacks, spell, etc)
- More formal Pallet with alternative pallets (sepia, nighttime, etc)
Don't feel pressured (Honestly, I love what you've done) but you did ask :)
