Its an interesting small game. Reminds me a lot on Mech vs Minions (board game). It took me a while to understand that each loop buffs stack, so I barely scraped by. I know its just a jam game but I found it to be quite shallow as I could just stack armor up as it persisted. I personally am not too much of a fan of that, I think it should have been reset after each encounter.
I found the UI design to be a bit weird and confusing, but thats probably just me. I think instead of the circle arrow in the menu, an X would have been sufficiant, and for starting a round, the good old play button or something similar would have worked better.
I hope this feedback can help you make improvements to your games in the future.
I think i sounded perhaps a tad too negative in here, despite the points I mentioned, it was a fun experience. It felt monotonous at times because it was just encounter after encounter but thats a jam, hard to make the biggest games in that time. Congrats on finishing tho! And good luck with your future gamedev journey :>
