Very good game! I didn't have a second player so I just played around with it but I think it would be fun with 2! I love the ice blocks that make you really think about how to position the die before going to a cannon!
One piece of feedback: when you are next to a cannon, you don't roll on top of it, but you slide into it, which conflict with the movement in all other places. It took some time to get used to it.
