Thank you.
Abyssal Infants is a little bit different in every version, because I was able to put more player and enemy bullets in the game.
MegaDrive: You can dash less often because dashing shoots additional bullets, but if you are starting loosing frames cause of cpu overload then a thunder will sound and your energy bar will be filled.
NeoGeo: You can dash more often. Also because there is no FM synth music but PCM and cause there was a limit in size not all songs are included.
PSX: You can dash even more and you can keep the dash button down. All songs are included but in PCM.
