I've tried it a little and yeah, definitely a lemmings clone, though maybe easier than lemmings (so far anyway?). It's actually closest to Lemmings 3 I think, with the unlimited walkers/stoppers, and some level showcases pick-up skills (most levels also start you off with set number of skills, so it's not all pick-up though). It looks like they score you based on number of bunnies making to the exit as well as how many extra vegetables the bunnies were able to pick up along the way.
The game seems to be taking its time introducing skills, either that or they feature far fewer skills than lemmings. I've gone through about 10 levels so far and I've only encountered basically miners and platformers (in addition to the unlimted blockers/walkers). You can't skip levels so I have to say it's taking maybe a little longer than I'd like for things to get more interesting. The bunnies also move a little slower than I like--even at fast forward they seem to be moving slower than your average lix or lemming. (Note: also possible maybe fast forward not working properly on my setup, nevertheless, the game runs smoothly with no lag, so at least at normal speed bunnies are moving too slow for me).
So I probably wouldn't have paid for the game, but as I've downloaded it for free thanks to Amazon, I'm willing to play it a little every now and then and see if the later levels become more interesting for me.
