Thanks FallingWallGames :) glad that you found the control intuitive once you got the logic! Definitely LOTS of polish to go on the controls (probably going to change the grid as well so will need lots more testing) but I'm glad you found them smooth, definitely what I was going for :)
Yeah plenty of room to go with the graphics too haha, the code is much more beautiful :P That's my main art form, but I do enjoy dabbling in pixel art. Find it relaxing, kind of like building Lego.
