UFOs are an interesting bunch.... they tend to wander around a bit, but
I was able to get through this one after several attempts. All was fine,
until that last UFO started dodging me. Thought I'd be the clever one
and do away with him with a few carefully placed prisms. WRONG MOVE!

Mom was
lurking about and decided to spring a few more on me!
So back to the original plan, leave one UFO and just dodge him, hide him,
or whatever I could to avoid him and make sure he avoided me!
Very much a fun level! I enjoyed this. The z-bots were there just to be
a nuisance, I presume?

(They do make a good nuisance, must admit)
Thanks for yet another quality level!
