Multi Input Maze is an exciting puzzle game that presents players with the task of navigating through a complex maze using various input methods. Unlike traditional mazes that rely solely on manual control, Multi Input Maze adds a dynamic twist by incorporating multiple input mechanisms such as voice commands, gestures, and button presses.
In this innovative game, players must utilize their problem-solving abilities and quick reflexes to decipher the intricacies of the maze. By strategically combining different inputs, they can manipulate the environment, open doors, activate switches, and overcome obstacles. Each input method offers a unique range of possibilities, requiring players to think creatively and adapt their strategies accordingly.
Multi Input Maze offers a refreshing and challenging experience for players of all ages, with its immersive gameplay and diverse input options. It encourages experimentation and provides a sense of achievement as players explore new ways to interact with the maze and progress towards the ultimate goal. Whether playing alone or engaging in multiplayer mode, Multi Input Maze promises hours of entertainment and mental stimulation.

I would recommend you don’t just copy and paste the code, just look at the code and type by understanding it.

<!-- Originally just an idea and excuse to test the gamepad API 🎮, this spiraled out of control a little into a multi-input maze. You can navigate trough the maze, depending on your browser/os, by: - clicking the up/down/left/rigt-buttons - the arrow keys on your keyboard - the WASD-keys on your keyboard if that is more your style - by scrolling up/down or left/right - by swiping if your device of choice has a touchscreen - by tilting your device (if your device does not reuqire special permissions for that (i.e. is an iPhone)) - by typing up(), down(), left() or right() in the console - and finally, by using a compatible gamepad, aka the original idea 🙃 The maze is randomly generated using the "recursive backtracking" algorithm. Found this to be the best option after starting from this SO-Answer: https://stackoverflow.com/a/23681987 and after reading this: http://weblog.jamisbuck.org/2010/12/27/maze-generation-recursive-backtracking" --> <div id="container"> <div class="mbox"> <div id="maze"> <div id="thingie"> <div class="emo" id="emo">🥺</div> </div> <div id="home"> <div class="emo">🏠</div> </div> <div class="barrier" id="top"></div> <div class="barrier" id="bottom"></div> </div> </div> <div class="controls"> <div class="buttons"> <button class="btn" id="bu"><div class="chevron">↑</div></button> <button class="btn" id="bd"><div class="chevron">↓</div></button> <button class="btn" id="bl"><div class="chevron">←</div></button> <button class="btn" id="br"><div class="chevron">→</div></button> </div> </div> </div>
