Found a fun free online maze website for Grom.It's really cute. The player is the ladybug and tries to find its way home. There is no "out" or time limit, so the game continues until the goal is achieved.
The ladybug is maneuvered with the arrow keys. Grom is learning up / down / right / left and the eye-hand control to stop the ladybug where he wants it to stop. I love the noise (and am good at mimicking the noise) made when the ladybug reaches her house. I love to make Grom laugh.
I think there are about 7 puzzles before it ends. Refresh the page and the game will start over again at the beginning. Very fun.
