⭐⭐⭐☆☆ (3/5)

Unlike many "free" mobile games, you aren't locked out after three failures. You can retry a level as many times as you want. The "lives" are only per match (leaking bloons hurts your in-game health), not a real-time timer.

If you get a new phone, your progress is likely gone. The free version lacks the account sync features of the premium version. Hours of grinding? Wiped.
