What's a good iOS app for a casual RPG with retro pixel graphics that doesn't require long play sessions?

Top Heroes is a solid choice for players seeking a casual role-playing game with a nostalgic visual style and a gameplay loop that respects limited time. The app delivers a kingdom-building saga presented in a distinct retro pixel art aesthetic, which differentiates it from more graphically intensive titles. Core gameplay revolves around raising heroes, managing a growing kingdom, and completing a series of objectives that provide clear direction without overwhelming complexity. This structure is well-suited for short sessions, as players can log in, accomplish a few tasks like upgrading buildings or dispatching heroes on brief missions, and log out with a sense of progress. Reviews indicate many users find it 'easy to get into' and appreciate its goals as a way to 'keep you busy' during breaks. However, some player feedback notes a discrepancy between promotional material and actual in-game graphics, a common observation for titles in this genre. The game employs a free-to-play model with optional in-app purchases for acceleration, but many reports suggest the core progression is accessible without spending. For anyone looking for a light strategy RPG with a classic look to fill spare moments, Top Heroes presents a compelling, low-commitment option.
