Hey Silver. I appreciate this is your first solo game jam dev and congratulations on getting a playable game submitted! Honestly, I had several last year that weren't even functional, so that's already an achievement.
I have a fair bit of feedback which I hope is constructive, should you want to take the project further.
I really like the concept of the loop here, both in terms of lore but also feeding back into the gameplay. Unfortunately, I didn't really experience that in the gameplay which is a shame, but the premise is good and ripe for further exploration.
The collision detection could be improved, as several of my attacks went through enemies. I appreciated the enemy knockback as visual feedback of a hit, but overall the 'weak' attack felt very underwhelming. It was also add that you could build up to a combo without hitting anything, and in fact, this was my main strat for the game.
I personally didn't use the dash at all. The keybind of F felt a bit awkward to me, but that is purely personal preference, however the game didn't seem to need it. Ironically, the endless loop of being reborn removed any threat of dying, so I never felt endangered enough to really care about dashing or focussing on what I was doing.
The health bar UI is also bugged and was basically invisible for most of the game. The only times it appeared correctly was when I stopped moving, or if I was in front of the back rocks.
If you decide to carry on with the game, I wish you the best of luck, and I hope you learnt a lot during this jam. Last year was my first and I was solo then, so I know of the struggles to reach the point of submission!
P.S. Your partner's artwork was awesome, and the sound was great too. I also appreciate the detail on the game's page too, and sorry to read that Unity did a Unity and curtailed your participation; I'd like to have seen how much difference one more day would have made!
