Thanks for your feedback!
Yeah, if I had more time to do so, I would definitely go and make the character movement better. The Overdrive bar fills slower because that was an oversight on my side. The Overdrive bar needed to fill like the LIMIT BREAK gauge on Final Fantasy games,
When I started doing so, I was trying to imitate the tier system of FF14 Normal Raids. Originally my idea was just having 1 leveling map + 4 raid levels with boss mechanics. But time was a constraint.
Also, when I playtested as the intended method, reaching Level 100 from Level 1 was an uphill process that took like 20/30 minutes and I felt like for a jam game, no one was going to invest 20/30 minutes looking at an autobattler. So I reduced all the game to 5 minutes from start to finish.
