I did enjoy this game but have a few suggestions which would improve it for me. Firstly, like so many games these days its just too dark, I struggle to see what is going which I understand is a key mechanic in horror games but I don't think that that is what this is. Secondly I think the shooting could be more fun and the penguins easier to kill initially. It felt more like plinking with an air rifle than shooting with a gun. THis did get better later with the grenade launcher and shotgun though. I wasn't sure what the objective of the game was other than to shoot penguins so I just kept doing that.
As I said I did enjoy the game but other than the fact that you are shooting penguins (random choice but fun) I dont see much connection to the theme or the education but if I missed something please say so and I will happily play again as it was fun.
