Thank you! Aw theyre little devils though, get too close and they fly right at ya and take off some of your health! Haha 😅
Yes, this is my first in-browser game made with Godot! But I have had similar experiences with lag in Godot even for downloadable games (oh god, in my unfinished game Morning Never Comes I had a REAL issue with this), due to shader and particle compilation only upon it being seen by the camera. I did actually do as you suggested, however - just probably not for enough of the particles & materials if its still lagging! In the 1.1v build, the camera sees the magic projectile particles, the cottage smoke, steam particles from the pie and several other shadermaterials for a few moments before the transition fades on and the camera pans over.
No idea why its still being so laggy, though I really should of done the same thing with the particles and VFX sprite material that appears when you kill a ghostie, as that... *really* slows things down.
Btw - if youre interested, and have accees to a keyboard with an "Insert" key - try pressing that to see a "secret" debug mode ;-)
