Nice concept with the health being on the die itself, the dice puns were also a nice touch. The camera angle could feel better, either widening it a bit or going full top-down, i felt it was too close, a bit claustrophobic even.
Some weapons can use some tweaking, the bow could have a lower curve or have the player charge the shot, so the arrow doesn't go over the head of the enemies, the sword is shorter than the enemies' one so I couldn't get around that, you could either make it longer or have the enemies turn around slower so the player has a chance to get around and stab with it while being safe.
A bit of an overhaul on the hitboxes could make it feel more responsive as well, often found myself not knowing if the attack did hit or not.
A timer of when the next weapon change comes could give leniency to players while keeping the randomness present, sometimes giving that kind of info to the players can make the game feel better, not showing which weapon, just letting them know when its coming
Overall it is a nice game and you implemented the concept successfully, its always nice to see an UE game around!
(My comments are aimed to aid finding out ways to improve the game, this doesn't mean its bad or that I didn't like it, the opposite, it was because I liked it that I spent time writing this)
Edit: Oh btw, I didn't manage to launch it through Itch's launcher, no clue how it works but just so you know
