Fun levels!

I still have plenty yet to finish, attached are solutions/backroutes so far.
I have 2 quick rages so far wrt the current version of Lix for SP mode (it's possible they only reflect my ignorance of certain aspects of the program):
1) inability to find out how many lixes have already come out is annoying. It's often useful to have the last lemming out of a crowd to do something, and if that something involves assigning a skill soon after it lands (eg. bomber timing), it's highly preferable to know w/o manual counting how many lixes are already out (and therefore how many more will enter, to better anticipate the entrance of that final lemming).
2) probably more the fault of the framework/libraries you're using, but in windowed mode under Windows, if I alt+tab to switch to some other program and then alt+tab back, keyboard input usually stops working (mouse input still fine though), requiring quiting the program and restart to fix. And of course, w/o keyboard input, I'm not sure how to quit besides killing the program in Task Manager (the close button on the upper-right of the windows frame is disabled).
