I can't really overstate how great the voices, music, and visual art come together in this game.
The gameplay is alright...it lags a bit on my computer, and movement isn't the smoothest it could be. But in the end, that didn't matter. You brought worlds you imagined to vivid life in this game, and it was one of the most immersive games I've played on Newgrounds.
Other games often try to hit this note; the author of a game will try to pull you in and make you really aware of what he or she was going for. This game hits it, solidly.
Work on your animation! It's really nice as is, but it's still a bit flat; more careful cel shading can solve this. Also, study arm and leg movement so that your cutscenes become even more vivid and realistic. The fact of the matter is though that the animation quality is already quite nice, and the flatness and limited animation in fact augment the girl's awkwardness and pull you in to the game more. Still, it's better when this is a stylistic choice instead of a limitation on your ability to animate.
I need to re-emphasize that every piece of music in this game fit exquisitely, providing the epic and yet serious mood that it needed. The plot meshes very well with the themes of abandonment and escape, and really characterizes Sellar for us.
And gosh, scavenger hunts are never this fun and multi-faceted in real life! Using many layers in the ways you did added depth, difficulty, and beauty to the environments, and that only increased with every level. There were little stories to be had by watching the animated environments as well, which was plain old amazing. The hint system, menus, and dialogue add polish on top of polish, creating a package that really can't get much better.
If this were a monetized project, or if you were working on a monetized project next, I would certainly purchase it. Beautiful.
5/5
