Introducing a Sonic fan game titled Sonic vs Darkness created by yours truly. This game is a remake of my very first Sonic fan game Sonic vs Darkness (2011), which began as a sprite-animated Sonic series project on YouTube. This demo features two playable characters Sonic the Hedgehog and Shadow the Hedgehog, and will include stages inspired by the ones from the original fan game. Like the original version, the gameplay style is inspired by modern Sonic games Sonic Rush and Sonic Unleashed. The download link is located above. Please enjoy.Disclaimer: This is a Non-profit fan-game project in development by Nefault1st.
