Very cool concept with switching between two worlds, if you keep working on the game you can definitely expand on this to make the interactions super interesting. I really liked the art style, especially the background. It was all really pretty.
Some feedback:
- The character's animations all look super cool, but the attack wind-up ends up making the attack feel kind of unresponsive. I ended up jumping over most enemies rather than wait for the really long swing time. The hit box also felt pretty restrictive, if enemies were moving towards me I think the wind-up of the swing combined with the small hit box would make timing attacks pretty difficult.
A really good start, I hope you keep working on it!
