A simple, nice idle game you got there!
The main problem I had with the game was that there is no way to enhance our click power. The only way to continue further at a great rate is dependent on weapons we buy and upgrade after a while. In idle games, clicking is encouraged by options that empower the clicking speed and power. I'd suggest you add another upgrade section to the game that has click upgrades rather than automated weapons so that the player can see a reason to click.
Solid entry, good take on the theme, well done!
