Having just played this I can't wait for more finely tuned version. I didn't have any performance issues but their are things in the test build such as low enemy/item count that make it feel a taaaad empty. Also little tweaks like letting the player control the pace of dominant scenes would be nice both for sense of power and to make earning health back quicker and Joe needs something to do to downed enemies if his attacks are going to end that way.
We are definitely gonna tune the hell out of this game. We are aiming for a polished experience, but it is gonna take some time. We just finished with our RAM fix and other major performance improvements. Now we'll be able to address issues with gameplay and combat, as well as continue to add new features, characters, and animations!
