I remember this from from the WIP channel on Discord! Cool concept, a good example if a very simple, but well-executed gameplay. I liked the creativity that went into the various enemies and weapons. The music was a bit hard on the ears for me, but I guess it's part of the sketchy style.
A simple but useful improvement that I would recommend is regarding the tooltips. First, I think they should appear much faster, I always wanted to check what a weapon does but it felt way too long. Second, if that doesn't go directly against some design choice of yours, I think you could also make the information about the enemy's weapons available (e.g. as a tooltip) because the player's choice to attack, swap or steal will always depend on what they are facing. Of cource, if I steal a weapon and swap to it, I can check it myself, but that's 2 turns lost just to get information.
