Hard, and fun! I like it

Very challenging, but a bit confusing ! I nearly didn't understand how to use all the formations, until finding the readme.

The readme cleared my problem with the enemies coming from all directions simultaneously. I couldn't figure out using the numkeys without that.
The idea is quite promising but the game itself is very repeating after a short while. Still great work for that short time.

Difficult, requires quick thinking. A decent graphical presentation (I like the soldiers the best).

If only they'd start shooting just a half second sooner after switching formations. ':)

This is a fun idea, although it does need some explaining and polishing
