I think it's technically impressive to integrate PvP and PvE into a game jam game, but the game is confusing and not very engaging for me personally. I was halfway through when I even realized that I was playing against waves of enemies and I was customizing my sword's stats in a meaningful way.
I don't know if the order of unlocks is random, but the first 'crafting' unlock I got simply allowed me to reset my craft, which didn't matter at all considering I basically had little to modify with.
Also, there might be some exploits going around because I went up against people with +999% damage or something ridiculous like that.
