Ranked one of the best apps for 2015, this game is absolutely captivating.
This app is a multi level game where you navigate a figure named Ida through various mazes.

These are not typical mazes, but optical illusions that change throughout each level. There is no way of losing or receiving a game over, you just need to get yourself unstuck or figure out what it is that is visually tricking you.
I was able to get through the game in a day, mostly because I was so drawn into it. I couldn’t help but stare it down until I could visually see what was stumping me.

Give it a try and let me know what you think!
