This game is quite fun. I like how melee attack is also a good movement tool, and that you heal on dashing through enemies.
Movement feels a little too hard to control. Couldn’t precisely position character. Also something is definitely wrong with holes on ground - either collider is too big or dash has some delay. You can try to dash at the very last moment in the tutorial area to see what I mean.
I also would like if you could continuously shoot while pressing LMB. Spamming it gets repetitive.
And finally, a little more visual feedback would do wonders. Like some animation or screen shake on getting hit.
Great job!
