Yeah so the skill tree does reset your game when you get a skill. Its meant to add more playtime, I just ran out of time to fully balance so like resting isn’t really worth it lol. It’s something I plan to fix after the nam tho.
I’m glad you liked the UI! UI is actually one of my favorite things. Since you were wondering how I did some of the effects, for example for the buttons, I made a scene for a custom button where the root node was a button and I added some tweens for when the mouse enters, exited, pressed, and released, all changing the scale of the button. I also added some sound effects so they are built into my custom button. Then I can just use my custom button scene for UI n stuff. If you have anymore questions tho, feel free to ask!
