It's alright but needs...
more complexity. I found that this was just too simple. Mainly because the enemies enter from one or two directions and just move at similar speeds in the same direction. The Two-Way mode is interesting, but because the enemies simply funnel to the center, it's a given how to place your towers making it far too simple yet again. You pretty much need only to symmetrically place your towers and you're fine. I like the idea of having a plethora of towers, but I think it would have been a stronger game if you cut down the number to maybe 5-7 towers and being able to choose which towers to add the the specific upgrades such as Instant Kill or Rusting. All in all, it's a decent game but there's not enough complexity to make it a great game and this one fits smack in the middle. That is why I give you an average score of 5/10.
