This was a really fun play! Definitely very polished. I love the art and music style as it really fits the vibe of the game. I do agree with someone else's comment about the upgrade cards feeling a bit off and a escaping the jam theme a bit. I think that the cards could be improved by making it more obvious that they have done something. Most of the cards were minor changes to invisible stats (things like probability or speed) and it was hard to notice a difference or feel like they substantially impacted the game. Other than that, this was a truly fun game with really impressive design. I can't wait to see future iterations! Congrats!
