gets boring around 10th level, as the gameplay is far too repetitive. also, I didn't really understand the boss..it dies in one hit in every level. Neither did I understand the bullets, I got hit but it didn't do anything..
good concept, terrible execution..first of all, the click and drag is dodgy..maybe its just me, but a lot of the time it doesn't work, and it also makes it hard to select anything else. The different mutations, nice concept, but then you have a 'Revive kills zombie' type thing where armoured guys are only good for purple hexes. The boss battles..and all the levels, even, were endurance, and the mutations failed in practice..damage+ would have made a great sniper, but for the fact it's impossible to command.
I didn't like how the places you clicked on didn't fit with the grass, especially on the defense/adventure place-it looked like someone was sticking posters on top of each other.
It's an amazing game with lots of functionality and stuff that you don't find inside games these days..but crappy controls and..lack of anything but trading makes it only a 2.
