I feel a kind of bad asking for enabling inputs. Now we can attack more times in quick succession, which is great.
Maybe that another solution will not have problem with this, but just in case:
-- if you double-click to attack it seems to do only one CTH estimate for both kicks - so you either double land or double miss.
-- if you do that and the last punch puts the enemy down, the falling down animation won't happen (but the tile is accessible ok, see pic).
