;IBJ Prevention by personitis
;v1.1 fixes a crash randomly (but frequently) happening from touching enemies.

;After the defined amount of bomb jumps, bombs give out, no longer propelling you upward.
;Every bomb jump, a counter is increased by 1, and is set to 0 upon touching the ground.
;By default, bomb jumps will work from mid-air morphs. It's possible to remove this feature by commenting out two lines.

;You can change the below value. Sets how many bomb jumps you can do before touching the ground agian. #$0003 allows for double bomb jumping. Anything lower only allows for single bomb jumping.
!BOMBS = #$0003
;You can also change the free space in RAM used for the bomb counter. By default it uses the Reserve Missiles address in RAM.
!COUNTER = $09D8
