The modified work of the first generation of Adventure Island, the game is very difficult. All the props in the original Adventure Island are preserved, including axes, skateboards, bullets that can knock out stones, etc. However, many of the game's level scenes use the second-generation Adventure Island, and even the scenes in Super Mary Brothers. The game's levels are designed to be more difficult, and even the original masters should not be able to easily pass the level. Overall, it's a very high-quality remastered game!
