The one good thing I can say about this is that it at least attempts to be a game with systems that have thought put into them. Many games around here that aren't some sort of VN usually end up being glorified slideshows with some numbers attached. All you do is cheat, or find the right place to click to make the numbers go up faster.
Aside from that, everything about this is janky. I wanted to give it two stars for being somewhat original, and having a custom engine. While that might be more fair to the developer, I think that reviews are for the players.
Combat in the game uses a grid-based, SRPG movement system. Oddly, movement tiles are hexagonal in the overworld, and square in combat. Which raises the question of why the dev thought two different modes like that made sense, but that you don't need a state that isn't essentially turn-based combat. Even in towns, when no one is fighting, you still have the same movement limits, and everything is turn based. Sometimes an NPC will stand in your way, and you actually have to select "wait" to skip your turn and let them move again. It's ancient, early NES-era tech where everything on screen just idles until the player does something. And NES developers did the hard work of figuring out how to do things better in about 1987.
Very little is animated. It's weird that nothing has a walk-cycle in an engine that's been under development for five years. Sprites and icons just slide around the screen, but are otherwise static. Dead enemies in battle are indicated by the appearance of a few blood splatters, and then their sprite rotates 45°.
Rewinding time is potentially fun. When you need to grind, or if the solution to a puzzle is unclear, you can just go back. However, there need to be some things that are retained or at least skippable after achieving them and rewinding. Whether that means the rewind power is more granular (executed in an area rather than the whole time period, for instance), or players just get to select things to retain, I don't know. What I do know is that nobody wants to keep killing Raving Rabbits and buying knives over and over as they search for the right combination of witches and powers are needed in 1962 Salem. Even worse, redoing the pearl quest.
Anyway, a 1-star game, but a grudging thumbs up to the developer for trying something different.
