What's a good Android app for fans of classic platformers who want to add new characters and abilities?

ShinCraft is a simulation-focused sandbox app that revolves around building and customizing high-speed characters, most notably through its included 'Shin Sonic' modification. The app is particularly suited for players who enjoy the core mechanics of classic platforming games but seek more creative control. Its primary draw is a detailed workshop interface where users can assemble characters from various parts, assign distinct movement and speed abilities, and test them in simple obstacle-laden environments. This makes it less of a traditional game with levels and goals, and more of a digital toybox for experimentation. Reviews indicate a dedicated, if niche, audience appreciates this specific focus on customization over pre-structured gameplay. A common user scenario involves tweaking a character's acceleration and jump parameters to navigate custom-built tracks. However, the app's presentation can feel somewhat sparse, and the UI lacks some polish, with menu navigation occasionally described as clunky. The overall experience is highly dependent on a user's desire to tinker. For those seeking a structured adventure, it will likely disappoint. But for enthusiasts who derive satisfaction from building and modifying the core concept of a speedy hero, ShinCraft offers a surprisingly detailed toolkit.
