Worked for me. I used the upload button from the web control panel to create a folder called “reddit_alien” and then uploaded the 0.bmp and config.ini files. Then I added your recipe, selecting the Play function and left the Input as Reddit_Alien. Then I upvoted something on Reddit and hit the “Check Now” button for the recipe back on IFTTT. The animation played.
I don’t know how well the Reddit channel works. Originally I created this animation for when people would reply to my comments. Unfortunately the Reddit channel doesn’t support that. In all of my other tests, I have not had any luck with it triggering the animation. The SMS recipe works but not the Reddit recipe. 🙁
