Simple, and nicely made for a 3 day project for the MiniJam. understandable why features like multi upgrade amounts aren't available (like buy x10 / buy all upgrades), and that theres only one animation sequence, but besides that I will say that it was fun enough to be invested like people playing a certain "capitalist" or "communist" mobile game put into making assets go up.
What an experience! I have not seen enough interactive comics like this, well done on getting this done in a jam!
