The solo game-dev journey - Clicker game

It's my first ever made game with Godot from scratch. I made all the arts and music in the game and used Godot standard assets. It's a very simple and stupid game and the code is still prototype level, not very efficient. But it works how it should (As far as i could test, if you find bugs please let me know!) and I made it in less than 10 hours.

The mechanics are simple. You have 3 buttons:

• Dev-time! :You work on your game and make money (I know it's unrealistic but it's just a game)
• Take a nap: this restores your energy a bit
• take a course: You spend some money and energy to take a course. 

STATS:

• ￥: It's your money
• LV: You lvl up taking courses
• Bills: Your daily bills. Higher is your level the higher the bills will be (Monthly course costs, stuff like that)
• Pay-day: You also have a day job so you get paid once in a while. The higher your lvl the higher is your pay.
• Energy: That's your energy lvl. You need energy to game dev and to take courses.

The win - lose conditions are:

YOU LOSE:
If your money goes below 20.000 yen.

YOU WIN:
if your money amount is above 30.000 yen and you are LVL 6.
