Great planning
Best plan for success ever: crank out as many mediocre games as possible with in-game ads, add high value medals to keep medal whores coming back for more. Watch the ad revenue pour in. Repeat.
Honestly, you are a role model for entrepreneurs everwhere!
On a serious note, this is the only game of yours that hasn't been a breeze to complete. As with other reviewers, the biggest issue for me is the platforms collapsing before you even fire. On level 11 I literally had to fire within the first second to hit the right-most Jack before he was blocked by rubble. I like your animation style and I am one of those medal whores I mentioned so I will continue to play your games ad nauseum.
