It's a Bloons TD! While 6 is definitely the best era objectively, I'm sorry, our heart will always belong to the 5 era. The fact it's SOMEHOW still getting updates on mobile (& the 500 ports that use mobile as a baseline) has to say something for its quality after all this time. That being said, we'd prefer it be a LITTLE more complex...

oh, look, Bloons Monkey City exists.
