Found a pony HTLM5 game based off the jousting of RD and Fluttershy, the objective is to avoid being pushed into the mud and push RD into the mud 5 times, a lot harder than it sounds Here's the link: http://ponyjoust.herokuapp.com/
Hooray! A shoutout to Google Chrome! I like how when you're about to win, Rainbow get's more resilient to you hitting her head with your own. PROTIP: Spam the UP arrow.
OW that was hard! My strategy was to hold down Left and dive at the mud, pulling up at the last second. She likes to follow you around the map. :Trollestia:
If you hit her as soon as she flies over to you on the head with your back, you can almost always knock her into the mud. You gotta be quick though. Preeeciise timingz.
Oh man! I just checked this out and it was pretty fun! I tried running away and then flying across the map and few times, then hit the breaks and watched Dash fall into the mud with a SPLAT!
