Awesome that you did a full on 3d fps shooter game for a game jam. But that is hard to make in a week, because of that it doesn't feel quite complete yet though.
- Jump is buggy
- Picked up more then 25/25 gems, but nothing happened
- Gameplay starts to feel like a walking simulator after a minute or 2.
I also don't quite get the corelation to the theme, I know it's your fears and all, but right now it feels more like: BOOM you're put into a world, shoot up some zombies.
You could make the gems a little more hidden, or behind puzzles to make the gameplay more intresting. The zombies can be a bit faster to.
