Hey Comodoro! Very nice game. I liked the take on the optional theme, very creative, and also the minimalist style.
I think the level design is great. You introduce the new mechanics in good pace, and by the time the game gets harder, it is easier and satisfying to think of a solution. Also, the Stored Memories mechanic is great, and really helps when the player forgets the path and don't want to start over or lose a life.
Played after the you fixed the bug on level 17 (I guess this was the glitched level), and got to the final. The last level has a minor bug where the maze don't fit properly on the game screen. On the fullscreen mode you can barely see the exit.
I think a score system would be nice, where using more the Stored Memories would decrease it and getting faster throught the level would increase it, but I'm not sure. Maybe there are other features that would fit better the game.
As a additional comment, I would like to say that this game is creative and a good puzzle game! Looking foward to the Play Store release and to further changes.
