Spider Swing -- 2

I need a Game similar like this from scratch [login to view URL] along with complete source code. Changes To be Made: 1. The Runner[Swinger should be a real spider]. 2. The Runner skins can be changeable. 3. The runner[spider] will be chased by the Bird. 4. Instead of enemies shooting it needs to have bugs upon hitting them runner should gain speed boost for some seconds. 5. If runner misses the bug, the bug will be eaten by bird chaser upon which bird will gain speed boost for some seconds. [login to view URL] needs to have 3 modes[if possible] a) Bird Chase unlimited runner[ends upon bird catches and needs to calculate score] b)Free Mode[No chaser just swinging freely and needs to calculate score] c)Levels with limited distance [at end spider will hide in hole and escapes, autogenerating levels] 7. Background should be objects like books,bottels,etc 8. Calculate score based on distance went and bugs eaten. [login to view URL] feel free to implement any ideas if u have.
