It's pretty good, basically just Lemming.Though it has it's problems.
1. The pause and fast forward buttons are kinda unreponsive at times, also the fast foward button doesn't turn off after you beat a level.
2. It's kind of hard to give skills to the Cavemen, I fell like the cursor isn't needed and should just be tapping the Cavemen to give them skills.
Also I fell like the Pause and Fast Forward functions need to be at the bottom of the screen.
