Interesting take on your "overworld" with something akin to a SMB3 type of map -- very cool to see that implemented. Your art is lovely, but I was sad when we temporarily transitioned to a black screen in between the pretty artwork, but that easily could've been a time-restraint that left some art unfinished.
There was a LOT of lore presented in this one that it sometimes felt overwhelming and hard to remember who was who / what was going on. I was also a little overwhelmed by the battle system, since there's not a tutorial, and everything seems to cost multiple different things in order to use -- including HP being required to use healing? Seems counter intuitive to me, but maybe I'm misunderstanding the system.
I think with some more time and attention you can definitely turn this into a pretty solid game, but as it is now, I came away feeling a bit confused.
