Nicely made.
Prbly the following would be worthwhile additions :
# Ability to destroy own unit
# More levels, higher difficulty with ability to create motherships as mentioned before
# A way to check your queued production / tech research.
Nice simple concept :). Overall well made game. Too short though, and a little too easy.
sbonagof, for sixth mission, wait for the guy to enter the building stairway. Then shoot him while he is climbing through the window.
Very nicely made game.
Concept is really good, though tha lack of a saving ability does make it a little painful, specially since the sequences take time and you have to wait them out.
Definitely gets 5 stars from me
