The pixel animations are nice, the ending CGs you get when you fail are not. Just a bunch of basic pictures and certain parts of the character are moved slightly via tweening, it's pretty basic. Fortunately, you don't lose the game when you fail, you're just taken to the town's inn.
The gameplay itself is kind of a pain. The movement of the character feels sluggish and momentum-based, kind of slippery, as if you're playing an ice level if you know what I mean. I never liked this kind of movement and it's the reason I hate ice levels in platformer games. The fact the entire game is like this is really irritating.
The basic attack combo is not too bad, but there doesn't seem to be a way to cancel the animation, and the character screams "Yaa" EVERY.SINGLE.TIME you attack. It's real fun hearing your character go "Yaa" a hundred times as you're chipping away at a Boss' healthbar.
There's also the fact that stunlocking seems to be inconsistent and even the last attack of the combo doesn't seem to interrupt the enemy's attack animation. That means that half of the time you can't do even a basic combo on the first enemy, a slime, because you might take damage and you can't interrupt their animation.
I don't know if this is a bug or it's simply RNG whether your attack will stagger an enemy or not.
A lot of the times the enemies won't drop anything anyway and progression seems to be done via quests so there's no point to killing every single enemy you see, feel free to just run past them.
Oh and the way items are dropped is a real doozy, too. You have to go the item menu, select an item and then select "Throw". Not too bad. right? Except she literally throws the item and it seems to be the only way to drop an item, so if you need to put an item in say, a chest for a quest or a pot for crafting you have to position yourself in a way that will ensure the item will fall right where you need it to.
The distance seems to consistent...for the most part, as sometimes the item will go slightly farther than the last time you threw it.
The jumping is inconsistent, sometimes you jump higher, sometimes lower. I figured that jumping when running is slightly lower than jumping when stationary, but no, it seems to be random. There was one time where I was stuck in a hole and I thought I had to reset until suddenly my character suddenly jump slightly higher than the first 10 times and I could get out.
Oh, and you can't rebind controls. I don't like jumping with Z and attacking with X, it's usually the other way around for me but that's just a minor gripe of mine.
Overall, eh. Too much of a pain in the ass. Don't bother, there's better platformer games out there, plenty of them on this very site.
