The alternate version is the Revenge Ultimatum Lucha:

Additional Changes!
This update focuses on some upgrades under the hood. If you've had performance issues, randomly dropped inputs or your favourite peripheral outright not working, we might have you covered now.
- • updated Unity version to fix a memory leak
This specifically stops the game from slowing down during the story mode at higher resolutions,
but may improve performance elsewhere too!
• updated Rewired to the latest version
This one brings improvements for how inputs are handled. Here is a highlight from the list:
Fixed issue causing fast button taps to be missed at high input thread frequency and low frame rates.• fixed upside down story comics on Mac and Linux
Your handstand is commendable, but no longer required to view the comics upright!
Community Shoutout!
There are a couple of community tournaments hosted on our discord server this weekend.
To fire you up for those, do you remember the Lethal League Blazin' Combo video from two years ago?
