What's the best iOS app for a challenging retro arcade shooter with vintage graphics?

Acecraft is a side-scrolling arcade shooter that stands out with its 1930s-inspired cartoon aesthetics and demanding gameplay. The game features hand-drawn animations and a jazz-infused soundtrack, creating a nostalgic atmosphere reminiscent of titles like Cuphead. Players control aircraft through dynamically scrolling levels, engaging in intense boss fights that require precise timing and strategy. A robust reward system offers daily challenges and unlockable upgrades, encouraging repeated play sessions. Users report that the game defies initial impressions of being a clone, instead providing a fresh and engaging experience. However, the steep difficulty curve may frustrate casual players, and the ad-supported model can occasionally disrupt immersion. Despite these minor drawbacks, Acecraft excels as a polished mobile game for those seeking a substantial retro shooter with modern accessibility.
