Fun, but only lasts about two minutes. Could be interesting in 2d or with some other gimmicks added.
I think it lasting 2 minutes is actually an asset. Even though a 2d version etc would be quite interesting, it is great to try such little nice things and then move on to one's day, not everything in the internet has to take that long. And unless one wants to show ads or sth, there is no incentive to actually make it longer anyway.
In 2D, it would become sokoban, wouldn't it?
No? Sokoban involves a single agent pushing blocks around a grid. No block can ever move without being pushed, and nothing can ever cross anything else.
In this puzzle, the only way for anything to move is independently, and everything is free to cross anything else.
If this was two dimensional, it would be the game Hi-Q, more or less.
Solitaire removes the pegs that are jumped over. If this was two-dimensional, it would be Chinese Checkers.
