A little late but I uploaded a review video to youtube and your game is a part of it! Check it out here:

I liked some of the environment art and the models, though I was really confused as to what I was supposed to be doing or where I was supposed to be going until I explored enough to reach the end. The map is huge, but most of it is empty. The movement speed is too fast and the jumping is too high for the zombies to be an actual threat, and I could just casually walk away from them. There was also no feedback when shooting zombies until they suddenly died, so it was hard to tell whether I was hitting them. There also seemed to be a bug with the music and it just kept getting louder and louder until I had to mute the game. The  UI on the left was also too small to see.

Ok, well, that was fine.

I was really confused, like, approximately the whole time.  There wasn't a lot of linearity because there were a ton of gaps in the walls, which was fine, but I was just confused by it.  I think there was a lot of polish that could be done to give this more of a gamey feel.  But I liked it overall!

Good work!

for some reason it felt like, I was entrenched in the ground.. the gun load and shoot mechanics were good.... although i was expecting AUTO RELOAD once my gun ran out of ammos.... I dint shoot any zombies... maybe they were all stacked one top of another.... but i liked the feel of it.

Who doesn't like shooting zombies? I did feel like the zombies were way too slow to be of any actual threat and the gun seemed to shoot off to the side of the crosshair. That combined with the zombies slow reaction to being shot I was never really sure if I was actually hitting them or not at first. I enjoyed all the different rooms, good job!

I can see how this is inspired by the walking dead episode :) There are some trippy rooms and zombies.. I like the different patterned rooms! Good effort :D 

Well, it's got a similar vibe to The Fantastic Game.

If I had to pick my favourite room, i'd pick the ｗａｖｙ room.

The AK makes me want to bunny-hop like Counter Strike, but the gravity is very high.

But yeah, you can break out of bounds, there's no real feedback when you shoot a zombie with one bullet, and the prison is large. Like, very large. You'd benefit from shrinking the map size, slowing the player down, and speeding the zombies up. This would make it more tense, because as it stands, you can trivially run past any threat.
