4種類の鳥と特殊能力を持つパチンコ型物理ゲーム

Build a browser slingshot physics game in the style of a classic bird-launching puzzle, with a soft 3D-looking look. Provide an episode select screen with a few level cards, then levels where the player drags back a slingshot to fire birds at wooden and stone towers guarding green pigs. Include four bird types, each with its own tap-activated ability such as a shockwave, speed boost, triple split and explosion, shown in a button at the bottom corner. Use pastel layered hills, rounded trees and a bright sky, with a cream-and-green interface. Add scoring, a level-cleared card with one to three stars and replay or next options. Destructible structures must react with believable physics. Deliver it as a web project that runs on a static host. Done means several levels are playable from start to finish with all four birds.
