Shrink the time! Makes a lot of sense for a bullet hell game, and a good fit for the theme.
The infinite field and variously sized enemies reminded me of agar.io (back when it wasn't thrash :) ) The screen effects were a bit too much IMO, but I liked them and HP being about "data corruption". Maybe exploring it a bit more would be fun, since I didn't get *what* I was playing as or against what (say, computer viruses?).
Thanks!
