I am glad you took my comment as constructive since that is sincerely what it was. I think these jams are a great way for us developers to evolve and having fellow game devs give feedback is invaluable in out pursuit of making our games better!
I didn't click the anvil. I just did a replay of the game now and yes that do complete the game thank you.
So if I get you correctly, you basically wanted to make a island survival game, but these jams restrictions made you enforce combat and ruins. :) I find that funny somehow.
As a first dungeon crawler I would say it is still decent. It is a bit of a tricky genre but it does have it's charm. According to the tile size it mostly applies to narrow hallways, but it makes it easier to navigate. I don't think you have to change that since you got other stuff thats more important to focus on.
