Hi! Thanks for the in-depth feedback, it's very valuable. We were pretty set on making a FPS but in the end there was little time for playtesting, balancing stuff and making the game actually fun and engaging. Anyway, we are happy with the result, it was a nice learning experience for everyone!
I did hear that you were set in making an FPS in the Jam's Discord Server, and while it's understandable, it's a type of behavior that I discourage. Sometimes matching the theme with what you've initially wanted to do is not quite viable, and you must be willing to make some sacrifices. With that said, I wish you luck with your next Jam!
