Thank you D7! I really appreciate the review.
I went ahead and made minor adjustments to things like some of the typos and early game values. I also removed any screen darkens to help with brightness. Anything that is still off mechanically will be left as is until rebuilt on a collision based software.
I can see how the battle system can very unforgiving, if you try again I highly recommend the Wait battle mode at first. So that enemies aren't taking priority while going through menus. You can change battle from Active to Wait at The End of Ends at a Dark purple crystal near portals. (Moved it up)
Also the optimize button is a trap! It won't help you most the time, you really have to look at the gear. Some set ups can just make things harder than it should be.
There are two major last bosses which weren't meant to be killed. It's technically not possible, especially not on the first playthrough. However If you NG+ a few times, there are several tools (some hidden) that might make it possible.
Anyways enjoyed watching your playthrough.
