The short version: This game looks great, with emphasis on looks great.
I like the aesthetics a lot. The color scheme is good and I seldom had trouble identifying game-relevant information, such as what I can stand on, what's dangerous, and what I can interact with. Character design is on point as well, with the two aliens/robots that I've encountered showing a good sense of menacing bulk. Animations are great; I love the "thumper" effect of the hammerhead alien, and the motions and types of movement available to the main character are beautifully animated.
However:
In actual play, the main character feels incredibly stiff. Having walking be the default movement makes her feel slow, and every time she jumps, climbs, pulls herself up, or drops down from a platform, it feels like I lose control of the game and just have to wait for a canned animation to finish. Also the jumping--an important part of a platformer game--is unsatisfying, offering no air control and poor control over jump height/distance.
Also, collision detection feels off in bad ways. I've repeatedly died to lasers and mines that it didn't look like I was touching, and in some cases with wall jumping, safely hit and stuck to a wall just below a mine and then hit it and died upon jumping away. In contrast, trying to grab a ledge to pull up seems too picky.
If you can tighten up the collision detection, and rework the movement so that the main character feels as fluid as she looks, this will be a great game!
