Woah, pretty cool, honestly surprised you could accomplish this in a week!
The game felt pretty good and is fun (and who doesn't like gamblin with the crates? :), and it could use some additional responsiveness, such as a translucent block placing indicator and easier inventory manipulation. Maybe I missed a key or something but it was very hard to go from inventory to equip area quickly (especially when under attack), perhaps it would be best to keep those elements next to each other.
Either way there is way more here mechanically than I could have ever foreseen, and I didn't really encounter any bugs.
