I got a bug at this particular point where the game would freeze for 20 seconds every couple of minutes. Once I attacked and moved to the next phase the freezes stopped.

Also, nothing I do seems to be increasing the 'level up' thing in the top right. It seemed to go up at first, but hasn't changed at all since my first prestige. Even before that point it wasn't really clear to me what was supposed to be causing it to increase.
One subjective issue that might be worth thinking about is how to visually represent the maths a bit more clearly. To give an example: I had tended to avoid levelling up the tickrate of the white cubes because it felt like I was limiting the number of high-value cubes that could occupy high-value positions. The same goes for the cube size upgrades. Of course, if you sit down with a stopwatch you eventually realise that you earn more money by filling the containers rapidly with white cubes than slowly with lots of a high-value cubes, but I don't think this is intuitive!
