I've now figured out the problem I had with my mouse input not working (as was the case with many Jam games needing Administrative input for some reason...) I have adjusted my Rating accordingly ofc.

I have played the game thoroughly again, got all endings (I think... I got 3 different ones.) 

Here is my review:

Summary

Adherence To Theme

• You need to pack your stuff and go to the bunker before the Raiders come and kill you. Good job on designing the game around the concept. Very well done!

Game Design

• The controls where serviceable for a first person game made in a jam. I tend to give 3d games with a lot of mechanics a bit more leeway for jams, since it's harder to get right. That being said, a sensitivity slider, even in the most basic form is a neat addition and will help feel the game a lot more polished while literally being just a variable that you control via slider UI.
• The hit detection needs a lot of work, at times my crosshair was right on the dude and my hit didn't connect, sometimes I was looking at another dude and hit someone behind me??? Same goes for the enemies but that is in the players favor and felt actually like it made the game fairer with them missing sometimes.
• The looting works fine for this Jam but the Items were hidden in plain sight due to the game being extremely dark. Atmosphere should not prohibit gameplay accessibility. I suggest looking at how other horror games do it. (In my brief research I found Amnesia, the crosshair switches to a hand to show interactable objects, Outlast has them flashing on the screen when the player looks in their direction and show a Text on screen and in Resident Evil 7 there is an Icon of the controller button that shows up above Items you can pick up. My personal first thought was making them glow and move in mid air, like old school pickups found, check at the very bottom, where I included image references, which link to gameplay videos without commentary.)
• The enemies behavior and AI was rather excellent. They where quite easy to predict when you know where they are. 
• The Level design was very flawed. There are several places that you need to look for in terms of Equipment spawns but it is extremely easy to get stuck and die. This does not feel like it was the players fault, rather than the designers.
• The jump does not help this at all and I found it to be rather useless. You can't jump on beds and chairs in a last ditch effort to get out of a room where Raiders swarm you and the whole system would need some more work. Perhaps designing rooms with either no Jump (making every room escapable in terms of Raiders) or with Jump (making the ceiling high enough so you can jump on stuff) in mind would help the game feel a lot better overall!
• I found the Key spawn in the Kitchen very quickly. There are other Key Spawns though, which I couldn't find after what are a total of 10 minutes searching. Perhaps it was a bug, maybe not, but making the key spawn in a fixed location like the Radio would make sense for a Jam game!
• From what I found, there where 2 types of Damage items. The knife, which deals 2 Damage and everything else. They were clearly identifiable as objects you stick to your enemies, which is good but the implementation along with the buggy hit detection felt a bit off. For one, I feel like they were designed as a crutch around the Level Design, rather than thinking of Player limitation when designing the Rooms. You may or may not have thought the player would hoard them in case he gets stuck and has to fight but the natural method of play was reducing the number of Raiders in an area to have a bit more time to look for spawned Items and that elusive Key.
• The Room layout was rather irritating at first. It took me 3 tries to even find the Room where the Radio was located at, this goes hand in hand with the Level Design I was hinting at earlier.

Originality

• The game's premise is highly original, nothing to add here. It is inspired in just the right ways and different in others.

Style

• As this is a 3D Jam game I tend to judge it with more leeway. All in all the graphics where nice, the models where nicely done, the animations where clear as to what the Player and Enemies are doing at any given time and there were some neat lighting effects on showcase!
• But overall the game was extremely dark. This ofc. was done on purpose but it inhibits the overall gameplay quite a bit. There is no flashlight mechanic, as you planned this sort of "hiding from Raiders" feeling but it was highly difficult making out Items in front of certain areas. Look towards the "References" section for some ways to improve this.
• The music was good. It fit the atmosphere quite right and was well toned, not Obnoxious, or overly Loud.
• The Sound effects on the other hand where a bit Loud to my liking , at least the Spawn sounds. This particular sound, was quite familiar as well, hmm I wonder where I heard such a noise before :)
• What would have been another excellent addition for this game would be footstep noises that get louder the closer an Enemy is to the player, as a way of Feedback. Really good Trick that one, helps with the atmosphere as well but I understand that there was not much time to implement such a feature, as this game is quite extensive already.

Suggestions

• Implement a way of seeing the Items more clearly.
• A better hit detection.
• Designing the Level with the Player/Enemy movement and size in mind.
• A bit more feedback on the Hits and Footstep sounds or other ways of showing the player danger is lurking around a corner would polish this up quite a bit!

Overall

This was a fun little experience, the Graphics were really well done, the music was fitting and you really nailed that "Oh crap, Raiders coming, quick grab everything I can and head to the panic Room" feeling!

With some of my extensive suggestions, I'm sure you will find some useful thoughts to implement for a future version of this or other games you'll do and I hope I was of help!

I "HATE" from horror games, that's why I made peace with the guys and found a new hobby. They liked my new hobby and wanted to give it a try. I believe we will make great pictures during the epidemic rofl

Good job guys, great game!

I couldn't play much of the game, I can't use my mouse to look around for some reason? I can only look left and right with the Arrow keys, which at first I thought was the intended method of input but then I couldn't look up or down, nor pick stuff up. 

So, in summary, I couldn't play more than 30 seconds without failing, but had no way to mitigate that. Graphics and Sound where nice though, so it's a shame.
