Amazing atmosphere, jesus christ what a thriller. The first time playing, I felt pressure but I didn't really know what I was doing and I failed in the end. Second time around jesus christ I felt the blood rush through me trying to get as much money as possible. Speaking of which, I think the grading should be a bit more lenient, especially considering that most likely not all players are even going to get even a good chunk of the total rewards since the main player moves as slow as he does.
Also, make sure I don't think the game was at 60 fps on my pc which has a rtx 4060. Make sure that optimizations are made for the game while playing because not everyone is going to have a pc good enough to play this game. Though I will say, it is worth the dynamic lighting to achieve what you did with the shutdowns cause that sealed the scary infinite abyss that was just in sight of the player.
Congrats on your game!
