Having completed the demo I just had to make an account to say I Really love this game! Art, music and gameplay looking great so far.
Took me a while to figure out some of the alchemy puzzels wern't done in more than a single movement.
Think you may have already said you were working on "defeat screen" art for the girls/monsters. Slight appearance changes at % damage would be a nice addition too.
It's nice to be able to increase and decrease the character's after amplification, I may just be blind but a way to adjust the monsters' after resetting would be nice as well (personally I prefer Vuu Amp 3+4, so being able to tune down nightmare 5 for example would be handy).
QOL: being able to see the mana costs of spells in battle.
Looking forward to seeing the next update, keep up the good work!
