Good job getting anything made within two weeks, it's shorter than it sounds!
Llama's already given a ton of feedback and I saw your devlogs, so I won't bother repeating things you've probably already fixed. Just one note on clicking is that it's always good to include a "hold to autoclick" (like 10x per second) function. Otherwise the player's just going to bust out their 100 clicks/second autoclicker and beat the game in a few minutes. Other nice-to-haves would be seeing the price of upgrades at a glance (without having to hover) and I'm not sure your save function works? I hit save after completing the game, but refreshing the page put me back to the start again.
