I like the small star you added to click on for gold.
It seems like the star gives gold (Level+power bonus x 100)? At level 20 the star gives 4,000 gold. This is good.
The star shows up very frequently. This is good because, at higher levels (level 20+) you need a lot of gold to get to the next level.
When you click the Reset button, it shows (YES/NO). This is good.
You may want to add a (yes/no) button for Quit. I was clicking while watching TV and all of a sudden the game shut down because I accidentally clicked Quit.
The farther the star is from the middle of the screen, the harder it is to see.
You might want to add an (Options) button, so that people know which buttons to press for certain things. H to hide/show the GUI, S to hide/show player stats etc.
Everything else looks good so far. Nice work on this update :)
