There's something about the movement... i'm guessings it's supposed to motivate using the dash, but that means dashing everywhere, and whenever i dash into an enemy and bullets are flying to my face i can't possibly dodge. The solution would be to parry but (maybe it's just me) parrying has a 50/50 chance of working.
I don't find guns worth using. They are imprecise and if there are different types like the tutorial showed i can't distinguish them, and therefore count the bullets, which will be important in the middle of gunfire.
I think the flashing lights and the colors, even when they are clearly a style choice, take away the information the player can get. A lot of times an enemy got past me because i didn't see it still alive after the flashing from another enemy and that got me killed. It definetly doesnt help that everything constantly changes colors, it's like you are asking me not to remember anything.
The character is small, i can't even tell what i'm playing as; i guess that's to maximize the range of view, but takes away personaity.
It seems like it has a lot of potential but at the very least it's not my cup of tea.
