Hey, thanks for the feedback!
I noticed the first problem too, the game is playing the text fadeout animation from the previous interaction and so when you interact with the next object, the text changes but it stays faded out.
I was thinking about making the dialogue text a different color, or maybe give it a background so you can see it better, but the different colors looked odd to me and I decided it would have to be good enough for now.
I'm kinda sad that I couldn't give the characters more dialogue, or that I couldn't give the player different dialogue options to choose from, just to make interactions a little more interesting. I was going to add a 4th suspect, which would've been in the bottom right house, but I didn't have any time left.
Unfortunately, I doubt I will update this game. School starts for me this week and my mom is already fed up with me being on my computer all day. I will keep all this stuff in mind for future games though. Thanks again for the feedback!
