🅰️ is cute 🌝 and unique and I think it would go great ❤️🔥 with the name 💕 Sweetheart! I too, think it has something to do with ❣️ lives. 💞 Bring 'em 💟 on!
I like the name Hearty Boost and think it should boost the standard number of lives you start with from five to some higher number. And since it would raise that level, I'd go with icon C with the up arrow on it.
