needs some changes....

good replacement for geodefense, but i agree that it would be more fun to pause and build/start upgrades for strategy. I beat all levels of beta except bonus, but gamma level 1 is unwinable by any means. I think it's a really bad idea to have everything move so fast. it's like entire waves can come through in under 2-3 seconds. it's less strategy at this point and just how fast can i repeatedly drop and upgrade towers, which makes it less fun then geodefense was. I also would like to see my high score compared to others, as well as see if i completed the level flawlessly, or with leaks. BUT its still awesome and i would pay $5-$8 for each level pack instead of $1 easily.

update: nevermind, I beat every level, including gamma and bonus. keep difficulty high, but maybe add an easy setting. The only way to beat any of these higher levels is to stumble upon the fact that any tower built in the exit wavy circle gets double damage. very unclear on that.

Love it! Addicting fun!

Really great game that has all the great qualities of a tower defense. This one is almost a replica of "geoDefense" which was a favorite of mine.

My main issue is that the first several levels are almost too easy and then I got to level 11 (treble clef level) and have literally lost at the exact same spot 32 times in a row, trying as many combinations of tower strengths and locations as I can come up with.

The Best Tower Defense Game

In the absence of other games like this that fell to the wayside of iOS updates, Neo Defense is a pure tower defense strategy game. The simplicity is elegant and the gameplay unapologetically scales upward as you progress, sometimes maddeningly so. There are a few features I wish carried over from the old geo defense games, but all in all this is a great game.
