Hi PixelSlop! Thank you for trying the game and writing this review.
I still have to find a good way to show the durability in a more direct way.
At the moment, there are one to three blocks that appears behind the weapon UI slot, but they are not that readable considering this is the main feedback about them. That said, I've uploaded a new version with a couple of placeholder tutorials to better understand what's what.
Again, thank you very much, I'm glad you enjoyed it!
