Two prestige upgrade ideas: Cheaper balls decrease the price of balls by 2% per level (Maxes at 50%). Cheaper ball upgrade decrease the price of ball upgrades by 2% per level (Maxes at 50%).
Just some ideas to add to the game. A more organized shop. Organized by herb and potion color. Make the sell prices update with your current multiplier. Make a selling option, comes in handy if you accidentally by to much of a certain potion. Maybe add a shop where you can increase the speed of how fast something is produced + how much each level will give. For example if something gives 1 per completion you can buy an upgrade that gives 2 per completion. For the worker make the auto sell start off. Had it on with a lot of stuff and the game froze for a minute.
When we start over to get the next bonus ive noticed that the sell price stays the same ( currently a x2 bonus and the sell price says 1 ) which seems a little weird. Although I have already tested it and I do get the correct amount but sometimes I feel worried and feel like I am getting the original amount.
