TLDR - Really enjoyed this game. Very well made with some nice dark humor. I rate it a solid 8/10. I do have a few small critiques though.
The movement is a little stiff, not sure if there is anything you can do about that but i dont feel much difference between the walking and running speeds not to mention your character seems to get caught on things pretty frequently.
The hallways are bit too cluttered. There is a lot of running back and forth in this game so constantly having to navigate around all the objects in the hallways gets a little tiring, that, combined with the movement and low running speed can make the game feel like its dragging on a bit too much. I'd suggest removing around 25 to 30% of the debris in the hallways or making the running speed a bit more noticeable while also allow the player a little more freedom when running into certain objects in the hallway.
Another problem was some events failed to trigger. I found myself having to ether repeat certain steps in a storyline or reload the game entirely. Big example was when i was making the cosmic brownies, i had to reload the save file 3 times for the game to finally allow me to bake the cosmic brownies. One more example was the snuff film route, this was actually the story line i wasnt able to finish as the game would glitch part way through the filming. i would kill the other "actor" and it would fail to trigger the next area. The model would be dead, but you could still hear the muffled moaning coming from the area where the model was, the game thought the npc was still alive for some reason. This would happen at random parts of the stage, sometimes for the first victim, the second, the last, etc. I would be locked out of progression and have to reload the save.
Overall though, its a decent game with fun ideas. I have been studying game design and programming lately so i know how tough these kind of games are to work on so dont take anything ive said as downing this project. I hope you will continue to update it. Youre doing good work, keep it up.
