I didn't buy any bee except the angel core bee. Buying 2 or 3 doesn't affect much. Eventually buying multiple of the bee causes update lag.
Eventually buying many multiples of the bee causes the graphics for the bee to disappear entirely, along with the benefit of the auto generation. Once that happens then no purchases of any bee will be effectual.
The overall movement for what goes on with the game is pretty rough.
There are no audio controls, despite there being a volume/music tab.
The graphics for the shop disappear if the page is changed
Assuming this is a first effort, continue to refine your work.
