A really cool concept and pretty solid execution, the blood moon is very creepy and the art is both cute yet spooky. The combat mechanic didn't work as well as the drilling mechanic, so I ended up just avoiding the enemies. I think the game could have used some ambient music to make it feel more ominous and less empty (or at least some tension music for low health), as well as some additional challenges such as craters so the jumping mechanic had a use. The gathering was pretty ominous, especially on the darker side of the moon, and had some nice intrigue.
Impressive and well done, I really like the overtly dystopian hemoCorp story the creators are writing, and I like the proposed "health-to-blood system" that is mentioned for the future in the description. If more development is going to be made on this game, I recommend finding ways to make that story stuff more apparent in the game, as it's really interesting.
