So I survived for a few days.

The first thing I have to say is that the music that comes on at night time should definitely fade in. The first time it scared the crap out of me haha. And I feel like the night cycle should end when the song ends instead of it looping again. 

With that being said I personally don't think that song in particular fits the vibe. My favorite part of this game is the environment and how creepy it is exploring. I feel like the intense music takes away form that, however if the enemy density at night was ramped up and constantly getting up behind you. That would be epic and scary!

I like the idea of the gun only recharging when the light is off but it did end up just making me not use the light. I think to get that idea across better you could full commit on the night time being pretty much pitch black. This would also make staying at the base which could be dimly lit even more important.

If you do keep working on this then defiantly flush out the upgrading the base part. Maybe you could set up turrets and barbed wire, recruit help. I'm thinking like the settlements from fallout 4.

TL:DR

Work on mixing the audio so nothing jarringly pops in and out. (otherwise the audio was really good, especially the ambient sounds)

I love the old school aesthetic and would love to see this world flushed out and filled with interesting stuff.

I think you could get away with darker lighting at night time.

Also if you enter any more of these GDFG jams, which you totally should, feel free to shoot me a build early so I can give you some feed back! I love your style and can't wait to see what you come up with next.

(I'm winterwitch in the discord if that wasn't obvious haha)
