I like the art style, glad to see a hot demon woman even though it's a superpowered setting. So far it's fairly run of the mill from the story but it's early on and at least it's all in proper English.
Fighting minigame was a bit dull. I guess I'm not into minigames much in general, but if it's going to be something so simplistic maybe have it last half the time as it's just a bit repetitive and boring.
So a dude in hiding sees someone turn up to a train station then decides that's so sus they'll follow them for an entire day then break into a house and confront them at gunpoint...
I'm never a fan of sandboxes, but faux sandboxes are just pointless... there's only ever 1 thing you're allowed to do, so just pointless clicking in between as things are entirely linear. Even if you ever do try to explore different rooms and things you always get the MC or someone accompanying him popping up and stopping you from doing so... I think only one of the dialogue choices had any kind of variable attached to it either.
