The game is nicely polished and works well. (no bugs found) Sound design is also pretty amazing! I admire how well you chose the scope for the game and then managed to deliver the game in such a great shape!
Some ideas I picked up along the way that could make the game even better:
I would perhaps welcome a way to restart the minigame once I figure out the controls.
The main gameplay are the mini games but I found myself spending too much time outside of the minigames waiting for a next chance. When you fail a mini game you just want to get that castle piece ASAP! :D
Completing the whole castle is quite hard tbh.
