Pretty fun game. Bit addictive, like gambling. When I first hit the jackpot the game froze for a few seconds. I would try using cpu particles instead of the gpu (if you are not already doing that). That usually helps web builds.
Hi Fokos, yeah sadly I'm already using CPU particles, its mainly a shader compilation issue, each new wheel also causes lag spikes, I wanted to add a robust shader compilation fix but didn't have time. Glad you had fun
