_________________________
Sonyc is a 1995 fan game/pirate game for MSX2 computers, developed by Elvis Gallegos and Manuel Pazos, and later ported to the Nintendo Gameboy Advance (not necessarily by the same developers). The latter version is less developed. 

The game's levels are arranged similarly to classic Sonic games: Of the 4 'zones', each is divided into 3 'acts'. The first zone has a grassland theme, as in most Sonic games. The second is a cavern that remains frozen despite the numerous magma rivers flowing through it. The third zone is an ancient ruins type level filled with sand, stone, and waterfalls. The final zone takes place in a forest that is similar to Wood Zone, one of the levels cut from Sonic the Hedgehog 2. 

There are also bonus stages, visited after defeating the guardian of each zone, which feature letter blocks resembling children's toys and in which Sonic has 60 seconds to collect as many stars as possible.
