Incredible game! Maybe a bug?
First of all, let me say that THIS kind of games are very rare (Zombified tamagotchi!?) which lead often to mixed experiences... The start was REALLY slow, (getting RP and waiting for the upgrades was kinda torturing D:), BUT (and a big but here), when I got past that point, and nearly had everything upgraded including RP flowing like a river, is where the true experience began.
Suddenly, after brutally slaughtering my fifth zombie, and trying every weapon, I decided to do EVERY pasive action and object before the game ended... where
(Spoilers ahead)
While teaching my zombie how to play the guitar, make him tune his favourite radio station and congratulate him for making a soldier salute was kinda funny and awesome. The part of the animals got me... showing him a cheerful bunny jumping on his hand and then giving him a dead one and watch him try to make it jump with by his own hands and explaining him that "he won't jump... he's dead.. sorry". Or giving him a dead dog and see the zombie barking at him so it could wake up was really (and I mean REALLY) moving, as the zombie would put the sadest face I've ever seen... I found the idea of explaining the concept of life and death to someone who barely understands you as a very powerful message, as where the zombie would only express raw emotions
(Or maybe i'm just tripping because of the 5 hours of playing).
Also, I can't achieve to obtain the advanced action with the Teddy Bear (and therefore, the cat one), I tried the rat, the bunny, the dog and the cat (alive and dead versions) both in Passive and Advanced actions (except the cat one, which it's prequisite is having the teddy bear one) and still I can't trigger it ... I am missing something? or is it simply a bug?
(End Spoilers)
To sum up, very interesting game, awesome graphics and animation, not boring neither exciting story and definitely superb voice acting.
