Very solid for your first game! It clearly was the clicker starter. One small improvement I would make is that game gets too easy after a few upgrades and you sit watching until wave 5. But very nice work. Congratulations 🎉
I realized that after adding waves haha, and I wanted to add more enemies, but I didn't think I had much time left to do the pixel art and then the coding, so I just left it as is! Thank you!
