This is a complete and blatant rip-off of Edmund's Platform Engine. You're even using his default graphics. All you've done, is expand the levels. I realise you have credited him but to be honest, you should almost credit him for making the entire 'game' as 99% of the work is his engine/sprites.
Normally I would support any fellow Game Maker user, but I really don't feel you have added anything to this ready-made Platform Engine.
In my opinion, this isn't really a 'game' you should be showing off. This is more like a practice exercise in using a platform engine, it's not a 'game'.
