Interesting little game, but I feel you should be able to click anywhere in the box and have it count regardless of the tree's size, and there needs to be more upgrades, as the game is very short.
Thank you for the comment! I have now made these changes and hope it makes the game better to play. This is just one of many short projects I'm working on to learn Godot, so I wanted it to be short and just try something out, but I have added some more upgrades to make the game a little longer too :)
If you have time, do you think you can check out my Badgen Clicker game? It's a very basic vibe-coded idle/clicker game that my brother and I made a while ago; my brother technically only added like a subgame and a few small things that I can't recall off the top of my head.
