Very fun! I can easily see this turned into a more fleshed out game with levels and timer mechanic, so I guess like an RTS. I would say this makes for a good level 3, felt a little confusing to jump into this not knowing how it works and then I kill all my carrots lol.
Also I think the number of carrots you have and the Sell button should be on the top right of the HUD instead of in the pause menu. Overall great game though!
