Thanks for your detailed feedback! It helps a lot :) I found all your points relevant, so I tackled them all and uploaded a new version.
- A bit unresponsive when clicking on fruits -> the fruits are not a bit darker while growing only. I also lowered the bgm volume and raised the sfx volume for the collecting noise to try and enhance the feedback for harvesting.
- Some upgrades can't be purchased although I have enough money for it -> I updated the UI to display "Maximum reached" instead of a price when the limit is reached. This was indeed needed.
- More suitable to have "final score" depend on the total amount of money earned -> I agree, I changed the score to be the total amount of money earned during the game.
- The 3 bugs you mentioned a few others are now fixed.
- Fun clicker -> I don't quite know how to fix that.
Thanks again, that was valuable. I'd very much like to try your game, it look very polished but I only have Linux and Mac machines at home. Can you provide a build for either of those?
