Yeah, I thought there was enough, but it does feel like there's a lack of ammo/health. Gonna try to fix that.
By the way, I don't think I'll do MM5STAX anymore. The layout idea was kinda crappy, so if anyone wants to try, go ahead. I do plan on doing MM3DW1X sometime though. Remember I ripped the unused level textures in case someone wants to do a level that wasn't done in the core (though most are Wily/Cossack/Mr. X stages).
