First, congrats for making this game. It feels ambitious, and you’ve executed it very well. I played for a bit more than an hour. Save/load doesn’t seem to be working (related to the permissions problems from before I guess), but if I do play more I’ll update this feedback accordingly.
What I liked:
Although the scope is big, there seems to be a clear overall vision and the game is directed towards that.
The intro story is quite dramatic, but leaves questions unanswered (intentional I guess?). I do want to know what it means and how Angel discovers it.
The characters and effort put in to make them unique and memorable.
Battle music that sets the right mood for a fight.
Special effects in battle. I can see a lot of effort went in here. Temporal Rift effect in particular is very cool.
The little bits of conversations with other students that explain the world, characters, battle systems, etc.
Teleportation crystal. Nice and natural movement mechanic that exists within the game world itself.
What could be improved:
In the initial intro ‘Esc’ should go to a menu. Right now it progresses the dialogue.
Option to skip the initial cutscenes would be useful for a second playthrough onwards.
One should be able to access the pause menu from a battle.
In the intro I thought I was Helen? Why am I controlling the Captain’s character? This felt a bit odd.
History of the Tower of Knowledge excerpt: hard to read as the text colour is similar to the background colour. Same for Quest text against the scene background. Maybe have a panel behind this text.
For the Student who says “Edwin, I bet 100 chips...”, the dialogue is triggered automatically when you run into them. Instead this should be triggered with Space like the others.
Found it odd to keep finding cash lying about: at home (in a shelf I think; the one where the father explicitly mentions is ok), in the gymnasium, etc. Would be nice to complete some task and gain cash instead. (Maybe this is how it is in RPGs, if so then it’s ok. I don’t play these a lot, just felt off to me.)
The battle system seems too detailed and tedious for this game. Is this kind of system standard in this genre? I can see the battles and character skill progression is a core part of the story, so I guess it's ok as well.
Overall this is a big project, and you seem to have made a lot of progress. Wish you the best!
