I gave this a try twice.
The first time I jumped straight into arena and tried to figure things out, and it was a bit rough. I do like the platforming and collecting all the nodes gameplay, but I think it just starts out really hard. My 2nd play through I played through the tutorial and it was a smoother onboarding but the tutorial ramped up in difficulty too fast as well. I think you want the difficulty in the tutorial to be easy enough in the tutorial that most players won't actually die. It also feels pretty punishing that the game kills you in 1 hit.
I think the platforming mechanics feel pretty good, but I also feel like I struggle with the sliding and jumping off wall to wall sometimes. I always expect to be able to wall jump out of situations and I end up dying.
I don't really get what the main character is, I think swapping it out for something more human, less alien would help with the appeal of the game. I think the art/execution of the game overall looks pretty good, everything fits thematically.
There are parts in the arena when I'm moving around and collecting the nodes it feels good, I just want to get to that satisfaction more easily at first. I would really like some intermediate goal to hit in the arena to feel good about my progress. I also feel like as I progress in the arena I never get a chance to breath, its just a constant ramp up in difficulty until I die. If you did something after they clear a room to show progress and give players a break that might solve both problems?
I think if you get the onboarding experience tightened up and make the loop more rewarding then I would have an easier time getting into this.
