Hey! Good question. These are designed for Forward+/Mobile, so there's no guarantee they'll work on compatibility, but some effects should work.
I deliberately chose to make them using Forward+/Mobile, because Compatibility introduces some hard limitations without any workarounds specifically so that games can run in the web.
That isn't to say that these are entirely incompatible with the Compatibility renderer, just that there's no guarantees. You can try grabbing the demos on the individual pages and see how they work in Compatibility, but since compatibility uses a different rendering pipeline the results can be weird in unexpected ways.
Hope I gave some clarity! If you like my stuff I implore you to leave a review, but no pressure!
