What's the best iOS app for a frustrating but satisfying physics-based challenge?

Rise Up! Protect the Balloon is a deceptively simple physics-based game where the primary objective is to tap and hold a shield to protect a rising balloon from a relentless barrage of obstacles. Its core appeal lies in its challenging gameplay loop, which demands precise timing and offers a tangible sense of accomplishment for each new high score. The game excels as a test of reflexes and patience, with a straightforward control scheme that makes it easy to pick up but difficult to master. A progression system and global leaderboards add a competitive layer, giving players a reason to chase just one more attempt. However, the experience is significantly impacted by its ad-supported model. Reviews consistently indicate that advertisements appear after nearly every failed attempt, which can interrupt the flow given the game's high difficulty. While the core gameplay is praised for being 'fun and challenging,' the frequency of ads is a common and notable drawback. For players seeking a tough, score-chasing arcade experience and who can tolerate frequent interruptions, it provides a compelling, if sometimes aggravating, challenge.
