Art is superbly good, game is functioning well on my potato pc unlike other games I have rated so far that has the same size. Game has a very chilling atmosphere onto it combined with the sound effects it is very good. Voice acting is good too WHAHHA sounds like it is comming form a walkey talkey radio or somesort it fits to the setting of the game and it doesnt break your immersion.
Suggestions I could say is to work on building and studying UI's a bit more, UI's are very important too, your main menu is bland too. it just has a button you could have reused some of the stage inside the game or your page cover photo for it, it is very good to make a big first impression you dont want to chase away potential players of the game because of that mistake. they say the line dont judge the book by its cover. but in reality nowadays first impression is the key.
Your game is pretty good and I see that you have put in a lot of time into it so I would like to say congrats to you and thankyou for letting me review your game.
