In short, this game is a challenge. It's not impossibly hard, but it doesn't hold your hand at all.
The only thing that I find negative about this game, is how much of a difficulty curve it is to get the controls down. It can be really frustrating to be confused as to how to do things, but once you do figure it out, it's only uphill.
Music? Calm, but alright, and it certainly achieves a tone where you won't get ♥♥♥♥ed off but you'll definitely feel like a wimp once it stops from you dying.
Graphics! Yes! I love the aesthetic! Very nicely animated, nothing feels too out of place and things that SHOULD pop out, DO pop out! (although it was a bit frustrating when a few things blended into the background but were hazards)
Gameplay/Game Design! THIS is where the game shines, Every level starts off with overwhelming information and danger, both of which you'll slowly learn over the course of your hundreds of deaths on each stage. After finally crafting a careful strategy as to how to get to the end of the level, you reach the bosses. At first they're not too hard, specially when you get their pattern down, but I can definitely not say the same about the later ones. These will test how quickly you can learn and adapt, because if you ♥♥♥♥ up now, it's allllllll the way back.
Again, a GREAT challenge, where knowledge and skill are both HEAVILY needed. Then there's different endings, but screw those amirite.
9/10: Fantastic, but VERY little away from being perfect. Give it a shot if you're into the Souls series style of things.
