I didn't get through the whole game and I'm running out of time, so here's what I've got so far:
- The characters have distinct personalities, but it's a bit wordy
- Lots of typos
- I appreciate the footprints for guiding the player. They're spread out a little too far apart for me to see exactly where I need to go next so I still fumble around a little but not for too long.
- I keep pressing Shift out of habit to run but get the party switching menu. I like that there's a quick menu for party switching but it's in an inconvenient place.
- I've said it before, and I'll say it again: RPG Maker is not a good engine for on-map battles. If this really is the core of your game's combat system, consider picking up a different engine. It's really janky right now.
- It's a little too easy to sequence break and get stuck. I entered the school's cellar and couldn't get out because Marsha (who I hadn't met yet) kept telling me we aren't done here - but there's nothing to do even if I smash all of the boxes.
I like your resolution to make a smaller game next time. I am frequently surprised by just how small "small" is, but a smaller, more polished game is definitely the way to go!
