Great game. The orange shirt guy was right though, the monsters are slow and easy to outrun. I expected some kind of boss fight in the end so I mostly Gordon Freeman'd through the monsters with the crowbar and had lots of ammo left. Maybe give them individual strenghts and weaknesses besides health so that different monsters require different weapons and the player is actually forced to use them.
The story was kind of predicable, but that doesn't hurt the score. There's alot of content in here for a jam entry and I certainly enjoyed it. Also, this takes quite some time to finish if you explore everything. Can't say that for many other games here.
I was kinda bummed you cannot take hazmat guy with you in the end, there is enough time.
Also: the hat! :(
