I’m a new flowlab user and as I was testing my game, it wont stop lagging to the point where the character dies while everything still happens in the background. It’s only on a visual and sound layer where it lags so I can still move, just not see it. <----- is the link to my game.

PS I’m using Firefox

The only lag I got was on the boss fight, it’s because the rocks don’t expire, and because they also don’t disappear when they hit the boss.

I didn’t get any lag either, except for the boss fight. @SnakeInMyHoot is correct that the issue there seems to be too many rocks.
