I like the idea of a survival dungeon crawler, but this one I personally thought had too many issues holding it back.
The combat feels out of place, but as you explained in another comment was added just to satisfy the rules. But I agree with the other comments here pointing out the improvemetns that could be made to it, if it isn't planned to be removed entirely.
A bug that prevented me from completing was the fact that starting a new game didn't reset health, so I would start a new game and die after taking a couple steps.
I didn't get to doing much beyond chopping trees down, fighting a couple enemies and cooking some bananas. I tried fishing but I don't actually know what I was supposed to do with it. Is fishing just random chance or was I supposed to be moving my mouse during the minigame?
I'm disappointed I didn't get to see much of this game, but I really like the concept. And I think if you gave another go at it next year or post-jam and added a decent amount of polish this idea could be great! Good work!
