Gotta say, really really interesting type of game, the fact that everything is just symbols works surprisingly well and everything looks very solid and well crafted; However I found the controls to be a little weird (Like all over the place) and even with the help screen a little tutorial would have been nice to get the hang of the multiple mechanics.
Also since the game is a little grindy, some music would have been nice, even just a repetitive tune; With that being said, for seven days of development it feels really complete.
