First of all, the art and sound is amazing and sets a very clear atmosphere for the game.
But I also really like the mechanics in the games and design choices you've made. In particular, I like the idea of that you lose if you don't pick your crown up fast enough - this forces you to plan your moves and think ahead instead of just blindly throwing it at the closest enemy. It's also very satisfactory when you place a well thought-out throw and you manage to take out a line of enemies while perfectly catching the crown with a dash.
I enjoyed playing the game and it definitely shows potential.
