Testing a Bush Leaves

I'm testing the leaves I made for the bushes. Compiled game working very good on my laptop, but the web version on my laptop little bit lagging, especially sounds, so ... right now I'm thinking how to fix that.

UPDATE:
I usually used Chrome browser, end there is a lagging in the sounds in my game, so ... I tested it in Firefox browser, and there no problems with the sounds, hmm ... it seems that Chrome have some trouble with Godot engine I suppose.
