If it happens to you like me, you will feel that the ui of the game seems quite outdated, here I have the best solution for it called Better UI. With this texture you can change the ui, configuring it to your liking, choosing whether to change the experience bar, the armor bar, the object selector, etc. You can take a look and download it below and remember that this texture may be updated soon ;-)
