Please add dash ability
Dashing would be redundant. You have the slash, which not only does it disables projectiles but also throws them back. It's difficult to use, but it's worth the pain and effort to master it.
Plus, dashing wouldn't fit the theme. I mean, the character you control is quite literally the interstellar Grim Reaper, a judge, jury and executor all in one. Why would someone like that doge out of the way? The game even says "Fear is not a shield". If that's not enough of a hint, then I don't know what is.
