Yeah, I made up my mind about the 5 days way too early and just stopped thinking about it after that.
I originally had plans for gameplay changes for each day, but never got around to making them.
There are still small bits of text info you can find though. The stuff you collect from rabbits and the text that pops up when you check the paper bag changes each day, all hinting at the ending reveal.
The gameplay is definitely a bit dull. But I feel like shooting the rabbits shouldn't feel too exciting, given the story's purpose. I originally wanted to add an ending where you shoot too many rabbits for no reason. The game definitely needs more horror elements to make it more interesting. But I got really burned out and couldn't add anything else.
Thanks for the feedback, I really appreciate it!
