Hah, good point on the sword as it does exactly nothing except being a nice animation. I know that the gameplay might be confusing as we barely managed to submit on time (the 15 min bonus saved us) so there was no time for making a tutorial (i tried my best on the itch page but it was t a lot). Ill try to answer your questions tho. The leaf bar that you mentioned is actually the health of the tree and the blue bar above it is its hydration and we didnt provide any way to refill the health. The saps duration is really short so i guess it just took a few raindrops and went away. And at last the tree growing… I have absolutely no idea why. I know that this game is kinda bugged and we would definetly fix it if we had more time. Thank you for your rating !!!
