This is absolutely my favorite thing that I've played for this jam!

The visuals and atmosphere are amazing, that goes without saying. 

The feeling of it is what got me, that sense of exploration was amazing, I was super immersed in exploring this dangerous and unknown planet.

The use of the darkness was really good for that too!

The level design for each area was wonderful and they really felt like their own contained sections, even if the game didn't call them out as such.

The core mechanic and the risk reward of collecting the fuel cells for your ship without dying were also really great.

The grappling felt a bit clunky sometimes, but honestly that's the only tiny bit of criticism I could find for this.

I love it! And I'd totally play (and pay for) a full game of it!!
