Sure! Here's an example of a near impossible game with 15 levels and a 10-minute timer, implemented as a single HTML file using JavaScript:
In this game, each level is represented by a pictogram (e.g.,
🌲,
🌎). The player needs to click on the screen to complete a level. If the player completes all 15 levels within the 10-minute timer, they win the game. Otherwise, if the timer ends, their progress is reset, and they have to restart from the beginning.
