Description

The Vowel challenge series, a long-time idea of mine, ended up in a series of rather easy levels, except for the U's:
A's (easy) [https://www.warzone.com/SinglePlayer?Level=1337662]
E's (easy) [https://www.warzone.com/SinglePlayer?Level=1337666]
O's (easy) [https://www.warzone.com/SinglePlayer?Level=1288249]
I's (easy) [https://www.warzone.com/SinglePlayer?Level=1337705]
U's (medium) [https://www.warzone.com/SinglePlayer?Level=1337811]

I am adding this bonus (semi)Vowel level dedicated to the Y. This is almost hard: few starting locations, and fairly central. Quite a job to secure some sides.
