The switch effect can be distracting but it also marks an important event, so I didn't really think about the distraction. For the auto shoot, I did consider it but I was scared that the player would have the tendency to just press it all the time and not really acknowledging the switch, giving it a boring kind of gameplay. It's one thing to hold down the mouse but another thing when the switch happens and you are in the moment that you just forgot to shoot, giving a frantic and fast gameplay. At least that's what i think :)
The rooms would benefit a lot from adjustments and a true progression but time was pretty limited for me haha
