As a person with serveral mental health issues, It was hard for me to play this game, but I had a lot of fun.
((Extra points for the Hamilton poster in Rae's room ;) ))
((And all the other little hints to it, hell yeah))
It's our first project! We're actually a group of four people, though, which made making the game an easier task. We used Unity and a third party engine (VN Engine) to create our game within our timeline (which was 6 months). It depends on the type of game you want to create, but there are lots of free game engines out there! https://conceptartempire.com/free-game-engines/
Hope that helps!
