Really interesting concept, there is a lot of potential here. Art looks really good. Gameplay is promising i think with a little more polish/juiciness it would probably feel amazing. As a minor nit-pick i think 5 weapons at the same time is maybe to much, it could benefit from having a system that allows to swap weapons like, picking a new one drops the one you have equipped (so if the player remembers where a specific weapon was dropped, and they need that specific weapon with urgency, they could go back, while being chased, etc) . Of course this would need a bigger scope from the one of the jam, so is more of a funny idea than a real critic.
Nevertheless, the game is really cool and complete, and you should be proud, congrats!
