Nice idea. You should prevent the frog from going near the edges of the screen, because it’s very anoying to get back to the center, due to the mouse going outside of the window.
Yeah, I realized dragging the cursor off the edge of the web browser game window freezes mouse detection, so I made the decision to have the drag "release" when the cursor leaves the game window. Not my best game design decision, but ya live and ya learn! Thanks for playing!
