This was really good! I'm honestly surprised how nice this looks for a jam game, great work on that front, really knocked it out of the park! The gameplay was solid and I enjoyed it quite a bit! I would have liked to see a stronger use of the theme, but that's mostly because by the time I realized what/where the kaiju was, the game was over. Also, a gem counter would be really nice.
Great work, this one's something to be proud of.
