Not very well balanced, kind of just a clickfest. Here's what my gameplay looked like: spend red to upgrade red production speed. This upgrade is infinitely repeatable, so spam click it until red fills in one frame. Then you have to trade red production speed for green, so spam click that upgrade until red no longer fills in one frame, then spam click red speed upgrade to get it back up again. Then trade green fill speed for whatever the next color was, then I got tired of spam clicking old colors to increase a speed value that's not even shown to the player so I could trade that for speed of a higher color, so I stopped playing. There were some other upgrades, but everything only costs one of whatever resources it takes obviously, so they were basically free, no real decisions to make there. Just kinda boring and tedious?
