To be honest, I find it difficult to deny this project (it's not a game in any modern-day sense of the word) a healthy recommendation. But after "playing" it for over an hour, I feel like I can't do otherwise. Actual Sunlight zooms in on the themes of depression, suicide and the feelings of loneliness and uselessness in a very, very direct way, hitting one straight in the face time after time after time. It does so alsmost exclusively by using text, text one has to scroll through by hitting enter again and again and again. There's not much more "gameplay" except for walking around your depressive character in a generic environment and talking to objects and people. This triggers ... more text ofcourse. Whole the time, one gets confronted with ideas and opinions about how bad/gross modern society is to its core.
Now I don't have a problem with text-based games as such - back in the 1980's several excellent games were text-based -, but the actual texts used here, and the way the different themes are handled, is really too grim and too "in-your-face" for me. Having experienced the loss of a loved one to suicide quite recently, I could hardly bear playing this. Themes like these presented in such a direct way as here, should imo be the subject of therapy-sessions in a well cared-for, safe environment. To punch this through one's throat as it's being done here, may help in making a point, but it's not healthy for the ones playing or rather reading it.... So be careful, I guess, and try this one at your own risk.
Personal appreciation: 5/10 (it does take some courage to make a "game" like this)
