Thanks a lot for the detailed feedback! I kept the controls at the bare minimum because I am still testing out this idea. Many players are still having difficulties understanding the core mechanics, so I am prioritising that first.
I will definitely try adding some cool techniques that the player can learn and master as they play on a future build. A useless quack button is also a great suggestion.
Thanks for letting me know about the performance issue. I will include a windows standalone build after I fix and polish this game a little more.
