Perspective from a game tester and user-experience designer.
Really loved the artistic direction. Need a number of experience improvements though.
When going to the setting menu, I couldn't figure out to close it on the opening title screen due to the close button being a semi-transparent unrecognizable symbol (one I haven't seen to represent "close" or "back" before) in the uncommon position of bottom left corner of the screen (the last place the average english-reading person is trained to look). Going full-screen made my cursor disappear and made it nigh-impossible to navigate menus while full-screen. The text changed fonts depending on who was speaking, but was not distinct enough per character to make me immediately recognize who was speaking nor convey anything about their personality the way that say choice of Comic Sans as font for Sans in Undertale helps convey about his personality, which is enhanced by the changing character portrait and sound-effects as text is written on-screen. Definitely recommend name-tags for who's speaking on the main game, but it's even more important when checking the history log in the phone.
After first run through, it appears the game crashes intentionally, but when I pull the game up again my first instinct is to hit "Continue" which actually just resumes from before the end of the first run. You have to hit new game, and it's quite awhile before you experience a difference on the second run. Second run could've started not long before the first dialog choice, like at least have it start in the bar as the conversation with the monster deer implies it will. Maybe have it go back there without the game crashing and having to restart it and select New Game?
Other experience issues are minor about the the phone menu. It's weird to have a button to bring you back to the main menu, and a quit game button right below it-- you only one and it should be the main menu. Both of these buttons are icons depicting the concept of leaving or closing right above the big close button. And the quit game menu, the "yes" option looks disabled, doesn't have an on-hover or on-click animation.
Overall, I was extremely intrigued and willing to power through these issues I described to see everything and test certain assumptions. Great start, would love to see the finished product some day.
