Thank you so much for the feedback and playing the game.
I initially thought of adding some passive items at the beginning and after each round before the shop, but ran out of time and it would have been a big part on the coding so decided to provide a clean version rather than a half working one.
Thank you for the review again! I plan to work on this game to add a story and make it a full game maybe even for steam if I can have that much time.
