Cool game and great jam :) How did you like working in Godot?
I like the visuals and sound effects
My feedback would be that I felt that I didn't have that many different options each round (I got 3 energy each round so I could either chose the 1+2 or the 3 cost items. So I would maybe consider how to add more interesting player choices in that area , increasing the amount of energy you get so you have more options to build in more ways might be enough!
Here is my jam entry if you want to try!
