Another really interesting entry- most of the ones I've been playing today have been pretty intriguing. I'm not really a fan of the dark storyline, but it is an interesting departure from a lot of the other games in the jam.
It's definitely rough around the edges. There's some very slow scrolling text at the beginning, and I accidentally skipped most of it entirely trying to speed it up. Calling out each character before their line is necessary in context, but super awkward to read. There are a few different art styles- the main one seems to be the mostly monochrome sketch one, which isn't really my style but looks good and works for the game. The pixel art in the menu screen is also nice, but doesn't mesh with the other style. The solid colour used for the tileset just looks bad and makes it impossible to tell wall from floor. There's also one stock animation which looks incredibly out of place.
Seeing a tactical battle system in RPG Maker was super cool, but the implementation is pretty flawed at this point. It's not clear why you can move to some squares and not others; I'm not sure if the overlay is actually broken or if it's just a contrast issue with the (temporary?) tileset. Mixed keyboard/mouse control is awkward, it's not clear who is doing damage to who when you attack, and some of the iconography is confusing. Similarly, it's not clear what "line of sight" means when the second enemy type is introduced. The screen that shows up just before an attack feels unnecessary and is serious information overload. Finally, some of the magic seems useless or at least not worthwhile, though with harder battles that might change things.
That being said, as a proof of concept it works. The tactical battle system is super cool and a major point of differentiation.
The anti-climactic ending and leaning on the fourth wall with missing features and testing stuff is not amazing, but it makes sense in context.
All in all I think there's a ton of potential here and I'd like to see it continued.
