On my game when i play on firefox the sound stutters and sometimes the game lags a bit,I'm not sure if it is because of my game but when i play it on chrome it works perfect.

Its specially bad on big levels and water levels,and its not related to audio size(i think) because i changed the WAV on the water level to a compressed MP3 file and that didn't fix it,when i remove water tiles the game runs better but the audio still stutters sometimes.

This also happens in the editor but its less noticeable,not sure if its a firefox problem,a pocket platformer problem or something that only happens on my game.

thx! :) that's a very exemplery bug description, haha. I will check if water causes any performance issues. It would help me even more if you could send me your game file via discord (the link is inside the tool). But that's optional :)

I made an improvement. It might not be perfect, but maybe it helps a little with firefox rendering. In general it's not a problem on your side. Appearantely firefox rendering implementation is just worse than chrome. So i would recommend doing everything in chrome, and recommend other people to play your game in a different browser than firefox.
