With the statistics I noticed that it just goes back in the graph whenever it runs out of space. I think an easy solution would be just to make it so when you use the left and right arrow keys it scrolls in the graph. It should just be a simple bit of code that makes it scroll similar to the main map
Game Bug that happened once: I just moved my Demo Booth out of existence in the aluminium shop by click move, moving it and then it disappeared and what was at my mouse was one of my fully upgraded CD racks.
Temporary Bug (Got fixed after clicking refresh): What happened was I bought a lot of Training Cubes because I needed to train all my worker so I could make high level 10 person games. I sold all but one of my Training cubes. This disappeared from the screen but I could still sell it. This made it so I could get Infinite money if I wanted. It got fixed by clicking refresh on my browser so this isn't that important but I am saying this anyway just so if the developer decides to pop on and look at his game created in his game corp ( ;) ) or wherever he made it, he could see what I had to say. Sorry for the large amount of text.
VERY good game. Only suggestion is the same as everyone else (add upgrades & more levels) HOWEVER I think you should keep this one and make a sequel rather than updating the game (I'm pretty sure you could if you wanted). Hoping to see a sequel with upgrades and more (harder because of the upgrades) levels ツ.
