find a better programmer
First time playing the game I had a massive pop up in the middle of my screen and a button below it reading "Go". It didn't go away when I pressed the Go, it didn't go away when I advanced to another area.
The thing that bothered me was that you shoot with the mouse, but you only allow us to move with arrow keys. When ever you add mouse control to your platformer, it's common sense that you let people use WASD to move the guy, you obviously didn't know this, now you do.
But despite all of the above, I continued playing. What made me close the game was the shooting system. You have to click exactly on the target for it to damage it. There's no bullets flying out of your gun, I guess you just have a toy gun and must concentrate really hard on a spot for the bullet to reappear there :P. I can't believe anyone would deliberately choose to make gun shooting like that, I suspect a lazy or incompetent programmer is the fault here. After the clickfest on hades, I closed the game.
You got good story and good presentation of it with the clips and the dialog, but it's a shame that it's ruined by sloppy execution.
