Hey! Really appreciate you buying my stuff and giving me such detailed feedback - that means a lot!
About the battle animations you mentioned - gotta be honest with you: these sequences were made for RPG Maker's side-view battle system, so they're only side-facing for now. I don't have plans to make front and back battle animations anytime soon since I designed these specifically for side-view games. Sorry I can't help with that request!
But yeah, flipping them horizontally should work fine! If you're making a side-view turn-based game, these should still be pretty useful.
Oh! And about which sprites go where - I can put together a detailed guide and send it to you. Just let me know your email and I'll send it over! That way you'll have a clearer idea when using them.
Thanks again for liking my art style! Feel free to hit me up if you have any questions. I'll keep making more stuff!
Hope your game development goes smoothly~
