Hey, six for effort.
It wasn't bad. The hitCollision was a little off in parts, especially when traveling at a terminal velocity towards a moving platform. I fell through moving platforms several times. Now, as for the levels. This felt like the original arcade version Donkey Kong, only without the sense of urgency and intrigue.
First thing that caused it to lose points, the storyline was half-assed, but instead of leaving us shrouded in mystery for just a single level, we get a whole plot synopsis of what exactly you're doing. Going to kill your Creator. Cool premise, but it should have been developed with vCam and an expansive world, not these dots and cannons, elements we've all seen before.
For a platform game to make it now, you have to have more than just a solid engine and some bad guys. For instance, take a look at Coma and K.O.L.M. and Endeavor while you're at it, just to name a few. These are the latest that have inspired me to make my own game. They employ storytelling techniques built around a platforming architecture. The experience feels more enriching, to say the least.
I don't mean for this to sound snooty or at all condescending. It has taken me WEEKS to even find a suitable engine to manipulate, as well as develop a plot that really drives certain ingame concepts.
But I encourage you to keep it up. The fact that you made a working Flash game is a feat in and of itself. Now just try to take it up a few more notches.
