It's really satisfying to dash out of the way whilst killing an enemy, more so when it moves you at of the path of bullets and letting said bullets hit other enemies. The player and enemies being subjected to the same speed limitations and bullet-weakness is helpful, as it gives the player a chance to take advantage of the shooters' blind spots and dodging out of the way of their shot bullets. It does feel slightly jarring that the player's can dash really fast in order to attack, yet their regular movement speed is extremely slow.
The red circle and red cones were useful for figuring out how to approach groups of enemies. In the moment-to-moment gameplay, I kept mistaking the red cones for the shooters' field of view. I think the shields' current direction is fairly obvious and that the red cone should be given to the shooters.
I got unlucky with a number of spawns where the shooters were already facing towards me and shooting at me. I think a short grace period at the start of the game would be helpful to give the player a chance to plan out where to go.
The bullet deflecting is useful, but figuring out the effective area and range to trigger it was tricky. It felt as though the bullet had to be very close to the player for the slash to register the bullet being deflected.
Overall, I like the dashing mechanic and gameplay loop, and would like to see the addition of sound effects.
A quick-burst hack and slash.
Minor edit: removed ambiguity about the red cone being given to the shooters.
