DISCLAIMER: This is MY opinion, only MINE!!! I don't wanna offend anybody and I don't want to hurt the devs feelings but I want to get this off my chest.

Now that the disclaimer is over let's start... I played the demo... I started and went for a few levels and I have mixed feelings. I will break it down into segments (or try) and YES I compare it with Ori cause that is a similar one just like this!

GRAPHICS AND MUSIC:

When I first seen this game I immediately fell in love with it and the graphics and music played a big role in it because both are similar to Ori. I know it is lower cost and the devs didn't have a huge budget but I adore these graphics. So both are 10/10 for me.

GAMEPLAY:

Fuhh... this is where the struggles come. I played a few levels and I love that I can grab onto walls. But I had an f*in hard time with flying and I quit the demo because of it more then one time. (I only played with a few levels and I already felt it).
Another thing is flying from a wall that you hang on. I noticed that till I jump away I shouldn't move the joystick and the character would fly then when I moved my joystick and pressed X but it didn't happen for a lot of time and I didn't liked that. I feel like that one flying period that you have is too short and mostly you end up falling. (Or maybe I'm bad and it is my fault.. I can live with that too).
The jumping is okay, there are more then one types, like long and short jumps, depends on how long you press the buttons but it is a bit cranky or at least it was for me.

LEVEL-DESIGN:

The levels are okay. I struggled a lot with the first level where you need to fly the first time. It was horrible at first but I somewhat got used to it and then two levels more and I am stuck with a level where I can't even see how to go on... so I am not particullary a big fan of the levels.

OVERALL OPINION:

I like this game but I feel like it needs a bit more polishing. I don't know if I will play it, maybe I play it or maybe not I didn't decided it yet. But I will definitely keep up with it.
I don't think it will be the next Ori but I can see that this game will be good with a bit of polishing till it releases.
I hope because I like these style of games and I want this to be good but right now I have the impression that despite it being really good in graphics and music it is a rage game for me now.
