Dash is a platform exploration game inspired by An Untitled Story. You play a a small, cute character who has a dashing ability, much like the Fly ability from the game FLail. This game is very good and a great cross between An Untitled Story and FLail.

On the final boss now. It's so difficult!
Anyways, the game is roughly 5 hours long if you're not going after 100%, on Normal mode.
