I think I liked the difficulty progression, though it could be slightly harder at the beginning. I can't say for sure because there was never a moment in which I died so it was hard to gauge.
I like the movement of the player and the overall look of the game, though I didn't understand when did I get loot. It seemed rather random by killing enemies with the dash. The dash you do to kill enemies is really cool, but maybe it could be a bit more exaggerated to add in the chaos, something like blur and some screen shake.
I also didn't understand a few things:
- The big square enemy when shot forced my aim to vertical for a while, which I supposed was some kind of stun. It also happened when I collided into them.
- After a few minutes playing occasionally some weird collisions happened, as if dead enemies left enabled colliders, as seen in the gif below.
- As seen in the gif, there's a circle that spawns in some places, I have no idea how or why.
Overall it feels good to play, although sound effects could add more juice, although I suppose you didn't add on purpose. Particle effects when you/enemies are hit could also add more impact to the gameplay. I'd like to do the dash on the enemy only if I am aiming at it, sometimes I'd dash unwillingly and it felt like it hindered my gameplan. A score or some other sort of sense of progression would be nice.
