I also extended one of the puzzles. The ring puzzle was originally just finding the ring in the freezer and taking it. This seemed way too easy so I went ahead and added more to it. Now when the player finds the ring in the freezer it's totally frozen. To thaw it out they have to run water on it from the kitchen sink. This melts the ice, but then the ring falls down the drain. The player then has to find the wrench in the bedroom to get into the pipes and take the ring.
This puzzle took much longer than it should have because there was an issue with the sprites. For some reason when I upload new sprites they turn out really weird. They often have weird blotches of color attached to them that shouldn't be there. This took me an hour to fix and I was only able to partially fix it for the wrench. I'm not even sure what I did, except possibly erase something that I couldn't see to begin with.
The game is now finished. It works from start to finish and I was able to add all the story elements and puzzles that I originally set out to have from the beginning. The music also turned out so much better than I had originally anticipated. I'm pretty proud of what has been accomplished in just 15 short weeks.
