As of 23 March 2025, the official game site http://nekogames.jp/g2.html?gid=CUSOR10_2 uses Ruffle to run the game. It was discovered by player Mavi_adam that objects that should be unloaded by changing floors can be referenced with the object selection when the Tab key is used (see linked video). What this means is that there is an easy way to bypass all gameplay and beat the game extremely quickly and effortlessly.

After clicking START, a player can Tab to the Level 1 Stairs Up object and then hold Enter or Space (or both simultaneously) to rapidly ascend floors. Then, the player can win by clicking the Floor 16 Final Pyramid, for which they can position the mouse prior to starting the game. Optimally, this can be completed before the stage objects normally become visible, and the total time takes less than 4 seconds to click Tab twice, hold a button or two, and click the mouse without moving it.

This situation will be treated like the "Floor 0" exploit (see https://www.speedrun.com/cursor_10_2nd/forums/kbnr4), and runs that use Ruffle AND the keyboard will be omitted from Any% leaderboards in order to keep the game competitive. Congratulations to Mavi_adam for finding this new exploit!
