Open-source credits

The EZOOP arcade uses locally hosted, modified game logic. No original third-party images, sounds, tracking, or external game embeds are included. The blue-and-white interface, controls, particle effects, and synthesized sounds are new additions. This credit is not an endorsement by the original authors.

Blue Bounce

Adapted from paddle-angle handling and speed progression in Jake Gordon’s JavaScript Breakout. The game loop, collision implementation, levels, UI, touch and controller input have been rewritten for EZOOP. Upstream sound files are not used.

Pocket Blocks

Adapted from rotation bitmasks, block iteration, movement, occupancy and line-clear mechanics in Jake Gordon’s JavaScript Tetris. EZOOP uses an eight-column, sixteen-row board with a new rendering system, input layer, scoring presentation and visual theme. It is not an official Tetris product and does not use the original project’s name as its game title.

Controller input uses the browser Gamepad API. Arcade gameplay uses standard mappings; the tester displays all exposed button and axis indices, including non-standard mappings. Physical-controller compatibility still depends on the operating system and browser. Device readings and scores are not sent to a server by this application. / Input kontroler menggunakan Gamepad API. Game memakai pemetaan standar; tester menampilkan semua indeks tombol dan sumbu yang tersedia, termasuk pemetaan nonstandar. Kompatibilitas bergantung pada sistem operasi dan browser. Aplikasi ini tidak mengirim pembacaan perangkat atau skor ke server.
