Firstly: that is some amazing crucial feedback, thank you for taking the time to write it!
Secondly: you are right, the ctrl does bother me too, even more so now it's also for the power attack and strong attack. I must figure a way to fix this sooner rather than later.
Thirdly: yes, crates and destructible should have random drops, so does enemies it's planned for next update, but you bring a good point and using environment to fight is a good idea and should be implemented a lot more! And puzzles is a great idea too!
Lastly: I love Zelda ๐ฅ
Thank you again, this is great to think about! I took notes and will see what I can do with it on the workbench
