Thank you so much for playing and for taking the time to give the devs detailed feedback!
I agree that shuffling is quite expensive and can feel unfair. But I'm not sure if just making it cheaper is the right thing to do. I will add "tree cutting" as a new, cheaper option for the player in the next update. That being said, the price was an arbitrary choice and could very well be unbalanced.
Multipliers are a great idea! I also want to implement some kind of permanent progression, so I definitely need a different kind of scoring system. Multipliers will be a significant part of that.
Different level themes sound amazing. They could even come with uniqe building and island shapes. That's definitely going on my to do list!
I'm always a fan of super rare items in games. Tree houses and bridges are very clever ideas!
Thank you so much for sharing your thoughts. Your ideas are fantastic and your kind words are motivating me to keep working on the game!
