16x power-up ultra-ultra-tower with 1 range, 3 reload, 12 dmg makes a sniper tower 540 times as effective as a normal one. and it has space for 20 of those baddies, meaning it gives a firepower of 10800 sniper towers on 36 build spaces :) :)
the bug with the towers stopping to target ghosts only happens when you have a tower selected and the ghost flies over the ghost-shotting tower, so make sure not to have anything selected during early ghost waves where you have only 1 high-dmg tower
i started out on kongregate sucking in all badges that i could get my hand around but games like that one make me doubt my sanity... i stopped playing it after easy badge 2/5
nice short concise game. there are too many space shooters out there which force players to spend 10 hours shooting stuff without end before you get the last badge... nice change of style here
