Well i had a game of hysteria, clearly a great scheme.
so at 7:00 i went for a zook skip cause i wanted to. it went to distance 400. and later on when i did it again it went to about 750. and then it exploded. how does the game decided how far and all that I'm confused.

most weapons explode after 10 seconds no matter what.

There is also a certain limit for projectiles - when they reach a certain distance off-screen, they detonate.
