I played it and I thought it was an interesting premise executed in an interesting way :) It plays well, the camera follows the rocket ship neatly, it looks nice and the astrophysics-based puzzling was satisfying to solve so i liked it a lot
I made a puzzle game too but mine's a crafting game where you have to craft your way from a larger inventory so that you only have one item, and it can be viewed here: https://itch.io/jam/gmtk-2019/rate/463986
