Well then, you just can't expect everything to go smoothly all the time... For the past few days I wasn't able to do much else as I spent a lot of time troubleshooting and fixing hardware issues on my end. Of course this is why I always try to keep backups (yay!) and so after many hours of OS installations and messing around, I'm finally able to get back to working on this.
Since there isn't too much time left before the end of the week, I unfortunately had to scale back some plans I had in order for me to be able to finish this and submit before the deadline. Thus the remainder of the progress I will be working towards will mostly be focused on bug fixing and very small additions.
I finally added in sounds to the game. There are now sound effects for movement, interactions etc. Aside from quick sound effects, simple ambient sounds for both the past and present are added in. I then went back to the first screen and created instructions for how to play the game.
The plan from now on then is bug fixing to make sure that it is actually possible to at least finish the game, after that is checking if the exported build will run. I could then probably call it finished and submit it. Hoping that no more problems arise!
