Wow, thanks so much! This is amazing feedback and I totally agree! Initially we had planned for the player to be able to swap the positions of towers that had been placed and also have a rare dice that let you choose which tower it would turn into, but unfortunately we just didn't have time to implement that stuff. We were honestly still looking for ways to give the player a little more agency and I think the idea of rolling before placing the tower is a great solution to that problem.
Thanks so much for playing and taking the time to give such detailed and constructive feedback, it's really appreciated!
