I saw a lot of your other replays, and this is one of the biggest ones, I appreciate that.
the main idea of the game with (solve the island problem by getting rid of bad plants), and the fun part will be to explore new ways of doing that, one of using your hand, one by using tool, anther by axe, and even the chemicals (last item in the shop) was just for that main goal of solving the problem.
but as you said, we couldn't implement this and deliver it to the player, the plants become a way of getting money, and gameloop become repetitive because we didn't add new mechanics.
thanks again for your feedback and i wish you luck in your game.
