This game from 2015 might be the first program I ever completed and shared with others.
Cookie clicker had gone viral a couple years earlier and inspired a number of other idle games that we were all playing at the time on our hand-me-down smartphones. For some reason I then decided to create a soil-based version (probably a mixture of wanting alliteration and playing too much Minecraft).
The whole thing is a single HTML file that contains a mixture of raw HTML/CSS/JS, which I remember bringing to school on a USB and distributing it to my friends where we would play it in class instead of doing work.
It should probably be noted I originally only added up to the "Soil Bulldozer", but when competition had people reaching that milestone I outsourced the naming of additional auto-shovellers to my friends (thus the breakdown in consistency and questionable choices).
