Lovely re-imagining of whack-a-mole. It's basic but well-polished - love the touches on the startup screens/main screen/high score screens, and the art style is surprising in that it's simple but has great sharp visual clarity. It does look a bit like you're smashing the poor lil' buggies with the scoop though!
I think it could use a bit more variety, as it has a tendency to overstay its welcome if using a keyboard - perhaps different bug types to force some live decision-making, i.e. wasps that you definitely want to let drown?
