It is always exciting to see players express how they chose to play the game. It is true that I left some cheese in for mana maximization; the dragon player especially is meant to be able to effectively break the system as a reflection of their power, so she becomes perfect for players wanting to min-max which I personally think is cool even if it shows the flaws in character's game balance when comparing them against one another. Each protagonist has appeals to different types of players and I'm glad Abyssnella clicks well with you.
I am aware that with Emily's help the players are able to roll through the festivals as early as they want which is not entirely desired from my end either. What I will likely do to cope is just add in jokes on how jacked/strong Emily becomes if players choose to play this way. Never in a way to interfere with this style of play, but more to poke fun with it since the expected play experience is for players to want to do as many as they can. It is very likely in the future I will return to Tey's method and handle Backup Witches in another way so that they still feel like they're able to help you; but this is the compromise I have for letting Emily be a true assistant of sorts and for Fii to be a leader in her own way. I look forward to making the game deeper as time goes on, and there may yet be time for these systems to be remixed as I receive more feedback. Thank you for playing my games!
