Thank you, we are glad you liked it. The numbers surely need a little bit more testing and balancing, it is definitely quite stressful to keep all the plants alive for such a chill mooded game :). The infinite money exploit is caused by a bug that is only present in the WebGL build and did not show in the Unity editor, so it slipped through our playtesting. It will be fixed in the next version. I am also glad you like the achievements, there's many more we would like to add to the game in future builds!
