First, thanks so much for playing! And congrats on getting all the evidence. :)
I agree it's a bit too easy, but it was made for a game jam, so I leaned towards making it accessible. I'll definitely work on balance and challenge if I work on a larger game in this style. (TBD)
As for your question about the ending... yes, there are two main endings! To get the "true" ending, try finding a different way to defeat the final boss. Thanks again for checking out my game, and leaving your feedback! I appreciate it.
