I guess there's no real point commenting because bots are downvoting any negative feedback? This is a very fun game and I'd love to play a full version without microtransactions and gambling elements.
Cannons start clumping together along the same trajectory after reaching more than 120 balls. I have 129 cannons, 40 speed, and 120,000dmg and stuck on round 2000+ because it appears I only have 1-3 balls. This was not a problem with 110 cannons.
