The graphics looked hella good and the gameplay was a lot of fun even tho tbf i didn't understand how it works exactly but i still had fun nonetheless, the game sadly look too good to be an nes game lmao but there was a lot of polish which added to the game feel, i'd say this game would work better as retro indie game where you destroy monsters with fast paced gameplay (the game lacks a little bit of speed maybe if you make the player and even everyone else move fast it would go crazy), you can try to work on the weapons more to make them have crazy synergies maybe so you can do crazy movement and combos (maybe that already exists but i didn't understand how to use the weapons well enough), so i encourage you to keep improving the game and maybe even make a post jam update since it def has potential
also if you do have a little free time maybe check out my game i'd love to hear your feedback and view on it :)
