Feedback so honest you had to say it twice! But thanks for giving it to me straight...truly appreciate it. And thanks for trying out the game.
Glad you liked the music, I love that soundtrack with this gameplay. And to be honest, the effects were a rush job, but I'm happy it gave the chaotic vibe.
About the gameplay, the battles are supposed to give you that tense feel like you're on the edge and excite feel when you take down a cluster, but if it's just leaning towards the tense side then I will look into it and make the necessary tweaks. The lag spike was probably because of a shader OOM issue which I fixed, but it may also be due to the camera shake on play zone shrink so I don't know if it's fixed.
I have uploaded an updated version, it's got updated UI, UX, post processing effects and I think I fixed the hitbox and hurtbox issues (my bad, i forgot to change the trigger collider sizes when I updated body child objects of the enemy and bullets), so I hope it'll give a better experience now.
Please check out the updated version if you get a chance and share your feedback.
(FYI, Fullscreen web version has framerate issues probably, so if you do give it another go try the web version without fullscreen or the pc version)
