Thanks for the great review, we really appreciate it :D
The correct thing giving not so much money is probably because of the streak machanic. There you get a huge money bonus for doing the right thing with the plant AND doing every minigame possible for that plant. Sadly we had not enough time to make that more clear ingame.
Disabling the tutorial after seeing it the first time is a really good idea, we somehow didn´t think of that :o
Also, if you wanna play the game without the story, you can choose endless mode :)
Hope that helps you too, as your feedback helped us a lot!
