I love the premise and style here, but the game is really, really rough.
With the volume at default, the music is insanely loud and driven into distortion (somehow). There is a volume slider, but it feels weirdly non-linear (in fact it's probably linear, it's just that audio levels aren't), and doesn't seem to affect in-game volume.
Which is kind of a shame, because although they're generic tracks, they're well chosen.
I don't know if the controls are designed for a different layout, but they're horrible on a US English keyboard. You have to move your hand halfway across the keyboard to punch or kick if you're resting it in the right place to sprint or shoot. Using Z and X for punch and kick would have been a much better choice.
I'm not sure what the point of having three different attacks is, as they all seem to do about the same amount of damage, none of them stagger enemies, and only one of them has range.
I wish the action was zoomed out a little; you can't really see far enough ahead to plan your moves.
I was never able to make it past the first level, because some enemies would randomly stop taking damage. I didn't really try that hard, though, because frankly it just wasn't fun to play. There were too many enemies and they weren't interesting to fight, and there was nothing in terms of narrative or progression to push me forward. The tutorial level at least had some height variation, but the first real level was very bland.
I liked the graphics. The style of the character art is going to be divisive, but I liked it. The backgrounds work well, too. Some of the animations are a bit meh, but the running animation for the main character was nice.
The UI could be nicer, but I almost invariably half-ass the UI to keep scope under control, so I can't say too much about that.
Technical issues aside, I think the biggest issue is that the fighting isn't fun. The emphasis is definitely on fighting over platforming here, and that part of the game just doesn't work very well. As I alluded to earlier, the enemies don't really react to your attacks or have interesting moves of their own, your own attacks are pretty boring and all do the same thing, and there's a dearth of effects to give satisfying audio or visual feedback.
EDIT: Finally, I know the main character is supposed to be beetle-themed, but I'm just not seeing it in her design or powers.
