Looks awesome!
Broke the game today (runtime in an unusual way, ram) with using contained explosion (thingy that makes shots HIT and then blow only after you stop, think I got the name right) a lot on the missile silo before the nuke appeared. When time came for it to do its explosion magic it stopped responding.
Also a lot of homing or maybe even g-link ammo at once on screen is a huge performance hit, happens with some rapid fire lot of projectile weapons the most, like maybe the triple machine gun on some spread weapons.
