Hello! The purple bar is mana (used for spells). The yellow bar is energy (used to study, gym, etc.). I need to improve the UI and use more color coding so it's more clear.
Sleep in bed to get energy. For mana you get it from sex, you can flirt with NPC's or unlock sex scenes. Right now the opportunities to get mana are a bit limited though, the goal is to add more with each update until there are plenty and you won't have to look too hard.
