I liked the overall concept, but the early game felt quite difficult for me.
The starting spaceship/area was very dark, so I had a hard time seeing what was around me. I also found some mushrooms that looked like something I could eat or interact with, but I couldn't figure out how to use them.
The first enemies also felt pretty strong when starting with almost nothing. In some of the early rooms I encountered 3–4 enemies together, and I wasn't able to clear them, so it felt difficult to get strong enough to progress.
The movement and turn-based UX reminded me a little of Crypt of the NecroDancer, with that very distinct step-by-step rhythm. Since there isn't really a musical rhythm tied to it here, though, the movement sometimes felt a little flat to me.
The atmosphere is very dark overall. The background music fits the game well, and I think people who like gloomy atmospheres will enjoy it, but combined with the dark visuals it made the game feel almost a little scary to me.
I think making the very beginning slightly brighter and easing the player into the first few fights could help a lot.
