Great concept. Would like to see some more polish. Dragging and dropping can get a bit annoying after a while, I'd like to just be able to hover over and press 1 2 or 3 for the lanes. Clicking the color indicator for a lane should change it. Tasks stack in a way that it can be hard to figure out how many there are, and important tasks can get hidden under unimportant ones. And losing can be a little bit abrupt, and it might doesn't tell you why you lost. Also, you can drag processes onto a lane and not have them actually move onto it, just stuck in limbo
However, despite all these gripes, the game you're trying to make is one I really want to play. There are many ways the game could expand, and a little bit of polish could go a long way in making this game one of my favorites. If we introduced multi-threaded processes into the mix, for example, that would be something quite cool.
I'm glad I got to play this game! Thanks for making it.
