So I found this game to be a fun little experience! Something nice to pass the time. It is a little difficult once it gets fast (maybe because I use touchpad).
Overall, I do see potential in this! One way to break up the gameplay is to add a "day/night shift" function, where Frog can clock out. This can ensure that Frog can keep his job.
One additional suggestion, I think it'd be funny if some cat boxes explode, and you'd have to put them on a specialized conveyor belt to deal with them.
Hope this helps!
