I appreciate the feedback, I'm busy adjusting the way one time gongs work, the visuals will be much clearer and there will be a reset mechanic. For example, you are traversing a platform and gain vision of a one hit gong, you will be required to go back to some certain point of the area, where you can then reset the gongs. I think my puzzle design in this prototype was just bad as well, and I've found much more interesting ways to structure the levels. I hope you try it at a further stage of development!
