malc -- thanks for the feedback. A wise person (ol'gramma) once told me that there's no "right" way to complete any puzzle. She's so right!

If you completed the level, then you did it the right way. Good going!
og --- Not while raking leaves, no way! Sounds like you completed the level though? Hope so. The UFO section is kind of a pain. But at least I didn't hide any mother ships, like some others do !
::::: SPOILER :::::
lillian -- one way to get thru the UFO room is to make sure the UFO stays on the right side. Don't let him cross over to the left,
except for one time.
One way to do this: wait until the UFO is in the upper right before pushing your box through the teleporter, and stay back. Wait until the UFO passes below you to the left, then quickly scamper through the teleporter, push the box north one space, grab the coin, quickly go to the right of the box and push it 2 spaces toward the water while the UFO passes from left to right. The deflector will now protect you from ONE shot, then quickly push the box in the water and scamper over to the left side, and start dumping deflectors in the water, being sure to avoid UFO fire. But the UFO won't cross over to the left any more.
There are other methods, such as self-destructing the UFO, but for my un-nimble fingers, that tends to be tricky. I hope this helps?
