That won't be happening.
Not because I think you've got bad ideas, but because we've already made alternative solutions in the upcoming update.
Rather than decreasing the difficulty through meddling with enemy spawn rates, I am adding some more tools to help the player strategize more and increase their damage output a bit.
For those unaware, the stat system is getting a big overhaul to make it more interesting. I'm combining the recovery stat with the stamina and mind stats and using that empty 6th stat slot for a new special stat, the new stat will give:
Swordswoman - the ability to increase the amount of spaces her basic attack pushes enemies.
Ninja - will now have a chance to apply a debuff to her basic attack at the beginning of her turn (blind, sleep, or poison) (upgrading her special stat increases the odds of this occuring)
Archer - able to raise her critical hit rate.
Just the new ninja ability alone will increase the damage output of the player by quite a bit and help decrease the amount of enemies able to hit you per turn IF used wisely.
Along with this, we're also adding in an outfit system that will allow the player to customize their starting stats a bit.
Thanks for the feedback though, I noticed this is the first comment you've posted on this site, so i'm happy the game means enough to you to express something about it.
We're still hard at work making the game, and it's not perfect and I agree the RNG can be BAD at times, but we're making things better as we go. With every update the heroines have gotten a little tougher, so by the end i'm thinking we'll be in a good spot.
