Incredible work for your first-ever jam! love the art and you managed to build a complete game loop, including a tutorial, that’s no small feat at all!. The controls felt really fluid, I loved it!

For feedback, I’d suggest adding some knockback when hitting enemies or perhaps a block mechanic. Also, when attacking while moving, the character tends to 'slide' on the floor; locking the movement during the attack animation would make it look much more grounded. One last thing: watch out for the platform placement, as I kept hitting my head on the ones above me. I really liked that you respawn on the last platform you fell from. Great job and congratulations! 

Good game! I found a few bugs with the player respawn,  sometimes I keep dying if a monster is attacking me during respawn. You might also want to add some ceilings, because at one point I flew into the void. Despite that, good work!
