This is a surprisingly well-polished game! I love the lil grandmas, Josette is a favorite.
It took a good bit of playing around to figure out that the only thing needed to get the waveforms in-phase was each grandma’s distance to the trap. But once I figured that out I was able to intuit how to build a strategy around catching the ghost.
The audio work, the UI, and the visual design is all tops. Very well done!
