I've seen plenty of dice throwing games but I like your strategic approach to it and the fact that attack and movement are one mechanic. I liked how you can hit multiple enemies if you aim correctly, that allows for some strategy.
Initially I thought it was an arena survival game but I saw the castle and got the idea. So yeah, making the goal a bit more clear would help.
The graphics is nice, and I think tweaking the lighting and some visual effects can improve the look further.
Good job!
