OHH that would make sense.
It basic just check distance between every bullet and enemy, if it's bellow certain value it accounts a hit. On my Linux Desktop worked fine but Web not so much but at the same time web seems to have lower frame rate (see how long yellow lines that represent flying bullets are ? on PC those are like 2 pixels) So that add up. Thanks. (I can't edit it now but maybe i will come back to this project in the future)
