Hey, gave it a run, I like the theme, indeed feels like the internet is trying to kill us!
1. Did the last minute before the Vortex feel exciting or just overwhelming?
It was cool, the horde ended up being manageable with the upgrades. I have experience with Vampire Survivors, guess that gave me some advantage though.
2. Do the new sound effects fit the music? Is anything too loud, harsh or repetitive?
I think it fits well.
3. What device and browser did you play on, and did it stay smooth when the horde got big?
A laptop, RTX4050, Edge, Win11. Ran smoothly
4. Which upgrades felt too strong or too weak?
The damaging aura felt a bit weak, I missed a weapon that could pierce through more enemies.
