Mhh yeah a nice idea! I also love how the dash feels at first. But the core mechanic falls a bit flat very soon. I think a basic issue of this game is that there is not enough player agency over the game events:
1) The camera does not let you see enough of your surroundings, 2) the player dash attack has an 'invisible' cooldown in which 3) enemies attack out of nowwhere and 4) you can do nothing to counter it.
For me, this means that, when I die, I don't think: "Yeah, well played, they really got me", but rather "hm, how did that happen? Not much I could have done here"
Hope this helps you somewhat! I like the idea! :-)
