Really enjoyed the arts for this one. The sounds and music also gives a really good atmosphere.
Likely has been said a lot already now, but I felt overwhelmed by the amount of mechanics when first thrown into it. Having made card games for game jams myself, I understand that it must have been difficult to craft tutorials after the time spent implementing the game itself.
About the game itself, although I do think it feels polished, especially for a short game jam, I also think it felt under-realized. While the core idea tries to marry the deckbuilder genre and the basebuilder genre, I think it's very clear that this was a card game first and the base-building mechanics feels very shallow. The bulk of the game is all about resource-management, but the base building aspect doesn't really interact with that part at all. The buildings (cards) don't interact with each others. I didn't get why there was a "Discover tiles" mechanics (except for the theming of being on an alien planet). The map's bottom part is also covered by your hand a lot of the time.
Overall, I agree with other commenters that this game has potential to be expanded, but personally I would try to lean more into the base-building aspect of the game to make it more unique in the genre.
