This was a really neat idea. Some interesting design with a solid gameplay loop. When getting quite deep into a run it became slightly tedious placing 4 grey bricks in front of the castle but definitely interesting to begin with trying to work out which formations were strong. I think it would be really cool to see this game with a deckbuilding twist to it, as bricks get destroyed they go back into your deck and you can progressively add more and more powerful bricks to your roster. But overall, a good adaptation of the Jam theme, well done.
