Yeah man, the mechanic was really good put to use in some levels. And it was actually fun to figure out how to actually use it.
And, you don't have to do any more changes to the game :D I appreciate wanting to improve it based on my feedback, but you can take this to other future games where it would apply, don't need to do it here haha.
Thanks as well for your comment. It was very nice. And good luck on any next project you might work on :D
