Good: Traps implemented nicely, design looks good
Bad: This level is just plain annoying, you have to pause too much to help you save the right target and you just keep having to start over and over again until you save the right % target
My goal for this experimental level was to have a level that gave you only floaters and was not completely trivial (i.e., not like Fun 2) and didn't just exploit a glitch to win (Conway's "Dyslexia" - nuke save% bug). This was the only thing that came to mind (and I sure am glad that the window object lines up perfectly with the lizard traps! Originally, I wanted one lizard on each side, but the one facing right didn't line up, only the one facing left). Sure, it's not great from a puzzle perspective, but the fact that it's annoying and difficult means I achieved my goals here
And there is a rhythm to it, by the way. It's easier to find the rhythm than to pause constantly (since pausing ruins the rhythm).
By they way, JM, "Try climbing that!" has 50 lemmings, not 80.
