Just pushed a new build with some target optimizations. Hard though on a web build, perhaps make sure you have hardware acceleration turned on in your browser. You can also play the game over on Steam to have a local version. Thanks for playing!
The new optimizations don't seemed to have improved things at all. And no, i don't mind sharing my PC specs at all. What would you like to know?
Also, while I'm down here typing this, the music from the game is playing without skipping so maybe it's a visual thing or an Itch integration that's causing the lag.
