I'm not a Tower Defense expert, but I've dabbled with several of them over the last few years. This was my first experience with any of the Sentinel series, and if they continue to evolve as they did from Mars Defense to Earth Defense, you've defnitely got a winning formula here.


Mars Defense was kind of a hard sell - mostly because I'm playing on an iPad, and the graphics were never really designed with x2 Zoom in mind three years ago. (I'm a gameplay-over-graphics guy anyway, and could justify that by imagining I was viewing the battlefield high from orbit, or maybe even from Earth - naturally the appearance of the enemies would be grainy!)

I liked the fact that the game pauses to give you a quick explanation every time you encounter a new feature (tower or enemy ability) for the first time, as well as the ease in one-touch-pause-to-play-later.


I jumped to Earth Defense pretty quickly after seeing it had Game Center support (I'm a sucker for achievements). About halfway through the first stage now, and I already noticed you addressed some of the things I questioned about Mars Defense - adjusting the costs so "triple upgrades" of standard gun towers aren't a no-brainer anymore, etc.

And once I reached the "teleport when slowed" enemies, I knew we had a winner. Any time a game makes me stop to (respectfully?) curse the designers, it's a good one.


But yeah, in a somewhat saturated genre, I like what I'm seeing. My brain is already trying to max-min the idea of what's the best ratio for building towers, building repair drones and just sitting back and letting interest gather.

And if Sentinel 3 IS today's "freebie," being a Universal App I'll pick it up in a heartbeat, and probably spend the $1.99 on Campaign 2 right out of the gate, out of respect for you offering the entire trilogy free of charge.


Good stuff, guys. (Or girls, I'm not sure who's on the creative team!)
