I finally had a chance to try it out (Android version) briefly and will try to write about it more later when I have more free time. Overall it has potential, although even playing just the first few levels I have already found myself getting slightly tripped up every so often, due to things working 90% like Lemmings but then not quite. For example, on the 4th level the natural thing a Lemmings player would do is to assign blocker and then assign bomber to the blocker to blow it out. However in this game it looks like bombers cannot be assigned to blocker, and doing so caused the blocker to be released instead (as if you simply click on them rather than trying to assign the bomber skill--of course, the blocker release behavior is also new to this game, though I don't see that as a bad thing once I understand it).
I also wonder if the game may be starting out a little harder than it needs to be. I haven't measured it for real but I think the limpychs move at a speed that's a little faster than Lemmings do in its game. And the ordering of some of the early levels are a little strange--eg. level 1 introduces digging and mining at the same time, and then level 2 just features mining alone and is more straightforward than level 1?
Anyhow, nothing so far that I would consider a dealbreaker, but I do think I need to spend a little more time on the game to get more used to how things work there.
P.S. When you pause the game while inside a level, currently you only offer options to resume, restart, and go all the way back to the main menu. There should be an option to go back to the level selection screen rather than all the way back to the main menu (just so I have to tap on "Play" there to get to level selection). You may also want to consider putting an option to bring up help when the player paused the game, instead of having to go to the main menu screen to get to that. Indeed now I think of it, there's really no need to go all the way back to the main menu from pause when it's more convenient to simply surface all the main menu options during pause.
