Thanks for playing! I'm glad that I was able to make something unique :D The upgrades make your harvester and planter bigger, so you can sow more seeds and harvest more wheat! (It just increases slightly each time though, but if you look at the front you can see it animating a bigger size each time)
There's definitely a lack of Gain Ground in it, but after scrapping 3 other ideas for being too boring I got the idea for the title and decided to make a kind of joke game out of it.
