There seem to be a lot of games lately that are recreated in a retro style, and VVVVVV is no exception. It has a relatively simple art style, but there is a unique gravity-switching gameplay mechanic that keeps the game feeling current. It also makes it brutally difficult at times, so even though this is technically a two-level demo, it will probably take you a while to complete. If you enjoy it, please consider purchasing the full game to support the developer.
