I find that if the game is going somewhat slow (especially in the latter levels) to actually alert a guard and then quickly hide while invis. Usually however, you can usually manuever through the crowd of guards if you just use invis and speed in the right way.
vengenceofchaos, this isn't anything new. Games on kongregate where you can buy extra currency with kreds have existed here for a long time. All of Kongregate's online games are free. What I mean by that is, you have the ability to play in any game you want without spending a dime, but that doesn't mean that you can't get extra stuff via money. Let's think about the developer. Not only do they get money per play, but also per kred donated (worth more than per play). Honestly, every game on kong that has an option of "buying things via kreds" has attracted a lot of ignorant comments like yours. If you don't want to spend, don't! It's the beauty of kong. every game is able to be played without purchasing anything, but that doesn't mean every single feature is free.

I agree survival mode should be added. It would be a nice interesting twist to see how far you can get. Maybe the map for it could be somewhat simple so it is easy at first, but a pain in the arse later. (Maybe a 'c' shape would be nice, like in compact planning but more thin and space for adding more and more towers as time progresses... so that when you reach maximum at the edges, there will still be room left to attack).
