Thanks for playing!
It's good to know the combat has generally gone down well with everyone so far.
I actually do have a few of those moves already integrated into the unused combos.
(Well, the Stomp is an optional unlock, and the Uppercut uses Down instead of Up at the moment.
Combos including directional inputs is part of the reason I've been hesitant to use the conventional Down and Jump combination to drop through platforms (in addition to wanting to cement the R-Bumper/Shift Button as the interact/traversal button). But almost everyone has suggested it so I may relent.
