I'm really surprised by the game's optimization. There are so many objects on screen, and I didn't lose a single frame. Remarkable.

As for the gameplay, it's pretty simple. I finished it in 12 minutes with an autoclicker, otherwise you'll be clicking A LOT. There are a few buildings and different units to buy, but they don't seem to be particularly relevant. You just buy and upgrade things, and you'll eventually win the game, there's no real challenge. Still, those 12 minutes were fun.
