Falcoware platform games, What i mean is that it takes falcogames Up + Right to make a jump, one would have to wait + Up + Right. Whereas 'the way' is Right + Up. e.g while running Right is already pressed so Up works correctly for a right jump.
To relate to the physics that i'm mentioning here try a nes game file like 'super mario.nes' through JohNess app on Android and see how a right jump works smoothly.
Forward this to falco game engine devs for improvement if possible. Thank you.
