Snailiad is a 2011 Flash Metroidvania created by auriplane. The game follows Snaily Snail on the quest to save Moon Snail and turn him into the legendary Sun Snail.

In this TAS, Mikewillplays and Dimuslv collaborate to achieve 100% completion—collecting every item—with the added challenge of not collecting items in "parallel universes". For further information, reading the authors submission comments is highly recommended.

There is author's commentary in the YouTube and downloadable encodes in the form of soft subtitles.

Note: This TAS uses a modified version of the original game that restricts it to 60fps, which is required to make it TASable. Information on modding the game is within the post here.
