Just updated the slot machine project:
Long story short, added moving clouds, animated butterflies, and a coin rain particle effect on big wins, as well as some minor bug fixes.
I'm getting some weird behaviour testing on my iPhone 5 though, in Safari and Chrome. It runs with a low frame rate and I got an error that said:
Framebuffer error (framebuffer unsupported)
I can't reproduce again the error so not sure how I triggered it, but curious as to what the frame rate issue might be. Will try to disable some animations and see if that improves things on that platform.
EDIT: I guess I got the error when running the project using the editor link so I'm able to reproduce it now.
