Thank you thank you THANK YOU for not having time limits or limited lives in this game. I loved being able to experiment - trying crazy things in the slim hope that they just might work, working things out eventually through a lot of trial and error, and not having to start the whole level or game again because I mis-timed my 89th attempt at a difficult jump.
I have HATED every single tower defense game I've ever tried, and almost didn't try this one because it was listed in that genre. But, WOW! This was an absolute blast to play. I really like the RTS feel. :) 5/5
