Hi Stonie,
This was my first itch.io game I've bought after I saw MrKravin play it. I was really wanting to play a word game and this had such a great plot to it :)
I also experienced this bug. I had just succeeded at the 6-word unscramble challenge with the shotgun pointed at the person in the middle (the 'mother'? People might be mistaking her for the 'sister'?). I completed it with plenty of time and the timer just kept going and ended up shooting the replacement TV after she was taken away. Then the the gun was taken but the timer sound effect just kept going for the rest of the game. This then counted as her death at the end.
Later, I solved this with plenty of time that I chose another to be saved (can't remember if it was unscrewing or crate result) and the shotgun event didn't stop until the next game started and the shotgun disappeared. It may be that this event when targeting the middle person only ends at the next game rather than when the player wins the shutgun game?
I think there was also one of these 6-word unscramble challenges where I put in about 3 different eligible words in a row and the game treated them as wrong. I can't remember the whole set right now but I remember that the last combo I tried was "Site", which it had all of these letters. Maybe it was just my eyesight reading the letter font wrong, but it was strange to get three different words on that one wrong. I was playing by keyboard rather than mouse, too.
Thanks for the fun way to play word games. I hope you implement a reset game function and to be able to skip the screen text into it, too.
Cheers!
