Characters

Art Description
Drowning sprite for Sonic. There's no water in this prototype so this is never seen.
Air bubble swallowing sprites. Again, no water.
Pushing sprite for Tails. While Sonic uses his, Tails will stick with his walking animation when pushing against a solid object.
Hanging sprite for Sonic. There's nothing to hang on to.
Minecart sprites for Electric Egg Zone. The objects haven't been implemented yet so these frames of animation aren't used.

Levels

Aqua Planet Zone

Loads of level blocks exist for Aqua Planet Zone, but given its early state in this prototype, many remain unused.
