(This is written based on the jam version, I also tried the voting phase version but it seems like it won't open) Edit: It worked once I tried again the next day.
I think this is a really cool idea for an RPG battle system, and I think it has a lot of potential. Even just in the original version I can see some of your ideas coming through, like buffing one person's stats and then giving them more turns, or reversing time on someone to remove their status effects. It would have been nice to explore a lot of that more, but it's understandable considering the time restraints.
Wish I could have seen more of this since it seems like a cool concept. It's important to have some pros and cons to some of the abilities to make it so that one strategy doesn't dominate the entire game as well. From what I played, buffing the test unit and giving it a bunch of turns was a pretty easy to defeat the encounters.
I also liked the designs of Era and the units in the screenshots so far, so I'm looking forward to the other types of characters we'll get to see in this.
