I found it interesting to play by myself, trying to get to the finish line at the same time with both cars, maybe it's an interesting follow up idea for the game =)

It's a simple game but a promising concept. Could be fun with more complex mazes and maybe some obstacles, even in 2D if it's online.
I imagine a 3D game with online multiplayer where you have to run (rather than drive) agains others to get to the center of the maze and has limited tools to mark where you've passed before and even leave misleading hints to enemies. Even better it it's in VR.
