Dear Tamara,
Thank you so much for this immensely helpful feedback! We really appreciate you taking the time to write out your kind words and thoughtful commentary. We will definitely reword the tree mechanic and implement multiple plank dropping ( because one plank dropping is lame and unrealistic XD). We will also ensure that the next build can exit the game smoothly to avoid manually closing the app,
Again, thank you so much for this feedback! We really appreciate it!
