The controls feel janky and the game feels unfair in some points of the game, but since arcade games are typically like that, that is actually a good thing.
Also, I feel a sense of Hotel Mario, Pacman, and Mappy inspiration from this. I like it. The only reason the rating isn't higher is when you run out of spray and the pests start swarming you, which may force you to restart. Possibly consider adding an elevator that goes from top to bottom floor.
