Thought a lot - and even managed to get quite a lot done!
Over the past week:
- For the first time, I was able to implement something similar to coin animation - it seems this should make it clearer why and how points are distributed + added growth and reduction animations to all numbers and progress bars. 

- While playing, I reached the maximum of 4 levels - and broke everything, it turned out that I forgot to made it:D - so now the game has a maximum level. 

- Added an energy icon everywhere where such points were indeed present + added tooltips - did separate research on them, it turned out that this helps a lot on an intuitive level to learn the game faster. 

-Slightly reworked the settings menu. 

-Added a dialog window about achieving the new level. 

-Added autosave every 3 seconds (although it might need to be moved to settings). 

-Many, many fixes :) 

+Added a bug - when opening the menu, the power bar resets.
