One of my favourites of the jam so far. A nice, simple balancing mechanic that adds constant tension. I really like the light and dark side of the planet mechanic.
I think it would be nice to better be able to see or understand the aliens' movements, but I really like the ominous tone that they just get you. Also, the perhaps some of the tutorial tips could be cycled in game as it is quite a lot to remember on the first few plays and I JUST WANA play all the games.
Great work and thanks for sharing
