Magnet mechanics are cool and you have a beautiful bamboo forest with decent pixel art on characters and objects.
Fight seems a little bit unfair that if they have a weapon with longer or equal range it's very likely that you will get hit first. Also trap doesn't seem to do anything than blocking the path.
And as others mentioned earlier it has a softlock issue when it comes to respawn. Kogasa died and I just got stuck while R reset doesn't really fix it.
Map design is definitely okay and entertaining to explore, and everything looks beautiful. It'd probably be more enjoyable if the combat could be a little bit easier.
