So I recently thought of something that could tie-in the Angry Birds Movie. It could be an endless-runner game that is still played horizontaly, and the characters run from left to right. Sort of like Angry Birds Transformers, but with jumping and dashing instead of shooting and transforming. Enemies could be hazards like TNT, a mob of pigs chasing you, etc. This game would probably work well with 3D models.
Characters
So characters could have their own abilities, which can be obtained via. collecting mighty feathers that just randomly appear all throught the map.
Red - Red shrieks loudly, which repels away any obstacles in the distance.
The Blues - Gets a bow and arrow and shoots 5 random objects on the screen.
Chuck - Dashes through 50 meters.
Bomb - Destroys everything around (but not above) him via. explosion. This does not affect the pigs.
Matilda - Throws an Egg Bomb wherever the screen is tapped which causes a sphereical explosion.
Hal - Pulls out a lasso and the player can now swing across the level until they fail by knocking into hazards. Once this is done, the player goes back to normal gameplay.
Terence - Causes a thunderstorm, which makes all blocks that appear on the screen soggy and now breakable.
Bubbles - Begins to inflate, but once he hits a hazard he deflates and continues on.
Stella - Blows bubbles that are filled up with the pigs, and the pigs begin to bounce around the level, destroying objects for around 4-5 seconds.
