Shame you weren't able to participate in a full jam, this has potential. I weirdly enjoy the combat, there's something interesting about how you can get hit while attacking, meaning you have to position yourself in a way so that the enemy doesn't run into you while you're attacking, the large attack hitbox helping a lot with this. Also hitting stuff does feel good with that cool animation of the character.
That said, it does suffer a bit from zero enemy variety, weird hit detection from enemies and bland level design but for something made in 4-5 hours that's more than understandable. I'd like to see it finished, but I assume you're more willing to move into other projects haha.
