I think that the difference is huge. You can compare the gameplay, playability ...etc.
Oh, and the engine. Yuk!!! You should see the code, that's insane; the player needs to check invisible hitBoxes even when it has to check if it's off-screen :D (so yeah, if you go out of the screen too fast, the game doesn't know you are out of screen). Also, the whole stage and all the animations are running no matter where you are in the map! The code was written everywhere, in MovieCips, subMCs, subsubMCs, we had to add a pause feature, sound on/off ...etc ...etc
