Soooo, this is Brackey's tower defense project forked from GitHub and tweaked to match the theme?
I can't say much about the design as it is identical to the source, but I like the starting screen that you did and the UI integrated in the game is neat, the atmosphere is also quite nice.
The gameplay is a bit dull for me, even on the lowest difficulty level, it is hard and I feel like my best chance is to spam reds and hope for the best each round, no real other strategy.
The card picking was a nice touch but a bit not impactful enough for me to see a big change.
Regardless, good job on finishing a game in 48 hours and best of luck in the jam! :-D
