oh man this game is brutal! i really dig it. the moody atmosphere, the sound, the "become conscious" button, it's a great scenario. i managed to get to wave 4 but those airstrikes ruined me.
i have two pieces of feedback: the placement preview is a little misleading since things get placed at the mouse cursor, which rests above the preview, causing a few misplacements! i also think the time to build structures could be reduced. i found that even with perfect timing you couldn't get defenses up by the time the first wave hits.
i hope ya keeping working on it! :)
