When playing the regular game version on the web (like in Armor Games and other sites), the level timer only shows while playing on speedrun mode, and there is no way to show it in regular mode.

To make ILs much easier to run and verify, I created a level-timer version of the game, which shows the level timer while in regular mode. (I also added the level name to the layout as well.)

This version is recommended if you want to do IL runs of the game. Keep in mind that IL runs without a level timer will be rejected.
