Is there a good iOS app for a retro platformer that's challenging but not frustrating?

Dadish 4 is a notable entry in the crowded field of mobile platformers, specifically designed for players seeking a classic challenge without the punishing frustration of some retro revivals. The core gameplay involves precise jumping and navigating increasingly complex levels, but developer Thomas Young implements a generous checkpoint system. This system ensures that failure rarely means repeating large sections, which is a common pain point in the genre. The challenge comes from clever enemy placement and environmental puzzles, not from overly precise inputs or unfair traps. The pixel art is vibrant and charming, with each of the game's 60 levels introducing small visual or mechanical twists to maintain engagement. The controls, a critical element for any touchscreen platformer, are responsive with customizable button placement, allowing users to find a comfortable setup. Reviews indicate that the difficulty curve is one of its strongest assets, starting gently but offering significant challenges for dedicated players in later worlds. A minor imperfection some note is that the checkpoint spacing can occasionally feel uneven in later stages, but it never fully undermines the sense of fair progression. For anyone who grew up with 8-bit and 16-bit platformers or simply wants a substantial single-player game without in-app purchases, Dadish 4 provides a polished, complete package that respects the player's time and skill.
