Glad you enjoyed the Jankiness,
There are IFrames - obviously not enough as it is a common complaint - but they are there... I really need to fix the stun lock, basically I plan(ned) to put 'Amy' back into the bunny hop backwards state after she hits you.. though it requires some engine rewrites so the "monster" dealing damage can get notified and know to change state, and I didn't prioritise it high enough to get in this release (too busy with wierd inconsequental details that no one beyond myself would ever notice ;))
