Cool entry! I love the visual style, though wish a little more had been done with the voxels - they were nice in the first room where it wasn't just sprites =).
Not being able to see the ground of the tile to your right/left made navigating the planet with lava nerve-wracking, I did walk into lava accidentally a couple times, though it was probably due to thinking I was turning when I pressed the Strafe key, not the visuals -_-.
I got the console dropping down and saying `Error in put_entity (lava planet - walking out): Invalid entity.`
For some reason the "space" key couldn't open the engine room, I was stuck for a while on that until I tried reaching for the mouse. Other than that, it played pretty well with just keyboard.
After the "oh no not again", I got lost, went to a planet I'd been too, and then it reset so I had to go to cryosleep again. After reading here, I guess that's the infinite loop (maybe mention it on the game page would be less jarring ^_^)?
I love the grid based space travel, it felt surprisingly good.
