I'm sad to say that you're quite spot on hahah this is the second time our programmers have ever used Unity to make a game, and we found out about this Jam a week late so by the end we were rushing and yelling at the computers while they were still learning some of the basic functions of Unity... the stress shaved off 20 years of our lives LOL
We'll definitely work on making the mechanics more user friendly like you suggested, and in hindsight I also should have made the items people interact with stand out more from the backgrounds as well.
Thank you so much for giving our game a try! We're really hoping to improve the game with all this feedback as well : D
