symax, i had that problem too, and on a lot of other games, but usually pressing the key he's going helps, say eh's going right press the right key, etc
try to press "Cinematic Mode" in top-left corner. Though it is not a fullscreen, but the size of the viewport will be much bigger.
Unfortunately, the fullscreen on kongregate is forbidden.
i die one MILI SECOND after final moment came in BH mode. what happened? I COULDN'T RESPAWN! BECAUSE I DIED MILISECONDS AFTER IT CAME! MAKE IT PERMA DEATH THREE SECONDS AFTER FINAL MOMENT OR SOMETHING, I DIED BEFORE TURNING INTO A BH HERO!
godamn premium weapons, at least ban them from BH Heroes, premium weapons mess it up so much! to the point where all they do is 5 shot you into your GIANT HEAD that has a GIANT TEXT in SHINY GOLD saying where you are...
full screen ain't full screen, if you click to go to full screen the mouse just stays locked but it doesn't actually go full screen. might aswell play in cinematic mode. i also don't get to see my health and bullets when it goes "full screen"
