i really loved it! i love the idea of breaking an ice, but the game has a big problem, is that the theme is not clearly used.
I think the game is very creative and fun, but it will be funner if it has more hammers (example: 1 hammer of 10, 1 hammer of 20, etc).
Thirdly, sometimes the hammers stay flotating and hindrance other hammers so it will be better if the hammers dissapear after 15 secs (using the command queue_free() and a timer in godot)
