This is impressive!
So fun to play around and hear the bit. Super original and clever!
The drag-n-drop was quite buggy, I even had a bug after a few stages where I couldn't pick one letter, so I had to restart. I think having the letters stay at place after respawning is important too. I know what I want to do, but I messed my timing, so I don't want to start dragging again. And you can put a reset button if someone wants it.
That being said, it was still hella fun!
Very well done!~
