This game was great! I absolutely loved how you used silence to make it super creepy; the message alerts even scared me because I got used to the silence of the environment. The amount of detail you put was super great to see as the hard work and love you put into the game was seen. (Video below if anyone's interested!)
The mundane tasks that are made creepier by the creepy wallpaper and radio was well done and the whole game was smooth and things that happened went well!
The only suggestions I have to improve the game would be to make more spooky things happen in the office; the first time a player plays through, they will be going around and figuring things out, would have been fun to see some spooks happen that would utilise the natural silence and darkness of the game to be scary! Another thing would be to make the picking up and dropping a bit better; it seemed a little janky but that could have just been me.
One last thing would be to foreshadow the creepy things that happen in the second ending; this would die in with my first suggestion. Maybe if the player takes too long, they will start seeing said creatures and that would tie in the end and also explain why there are those creatures without giving an actual explanation and tie off the game in a circle.
Other than that, it was a great game and loved how the time in the game kept going even if the player is just walking around doing nothing and how wholesome and helpful the boss of the company is! Loved the silence and lok of the game; you did a great job on it; it was both challenging, spooky and fun!
