So fun, thanks for sharing! I'm feeling some nostalgia. The first game I ever made was also an ant defense game. You use a magnifying glass to protect your tomato at a picnic. As you get to later levels, the ants get bigger and the sun starts to set, so you have to buy upgrades.
I wrote it in Java in high school back in 2006. The site I hosted it on in high school is no longer live. I put it on Replit a few years back, but I no longer have access to the account, so I had to fork the repl to play it again. Things change. Hold on to your code. It's fun to revisit old programs!
