This is awesome. I was a bit skeptical at first, but as soon as you survive those first couple waves, the cavalry starts to roll in and the game gets better and better. That first minute really makes you appreciate the extra numbers, too. I really like how all the soldiers don't shoot in unison and take a second to adapt to what the player is doing, made it seem much more like an army instead of a hivemind (though maybe a hivemind would be more accurate for insects). This game also had a really high production quality, all the artwork looked super polished. If you ever come back to this, I'd recommend letting the player keep control when they whistle. Near the endgame where I was whistling every second, I had a lot less precision with the controls. Other than that, great game!
