Did all 5 levels.
In a Game Design stand-view, IMHO its good. Main objective is go to point A to B, to reconnect with a loved one. You show level mechanics level by level. I think the game would shine more if you added more level mechanics like the blue squares. Also the last level would be interesting if a little more short.
Fun is there no need to say more.
Innovation is kinda a difficult to say, so average?? It would be smashing, to see like ripple waves when touch a wall and with that we would have to navigate.
Theme is there. Lover is part of love, blindness is a mechanic.
Graphics are simple shape objects, which just could have used a little more texturing.
Audio is okay. I'm the last person to judge someone audio.
Hope you had fun during Jam Week :D
