General feedback about the executable: I would save your package (Windows No Editor) underneath a folder that has the name of your game! I downloaded another Unreal game that had the same issue.
Really enjoyed the level and character art! They look super good and mesh very well with the world! I also enjoyed reading about how Marvina enters this world and the fact that she uses a racket to defend herself. I did notice that the capsule colliders on enemies show up in game. Was this part of debugging? Also, there were a ton of enemies spawning in one location so the game was pretty difficult on my end (ended up getting ganged up by three of them and dying). So I would make the game somewhat easier. Picking up items also does not destroy them in the scene so I got confused on whether I picked up the powerups or not.
Also left mouse click does not attack, right mouse click does. Just wanted to mention that lol. Overall, the style, narrative, and the environment look really good! You did a great job on that end! Gameplay is mostly solid, just a few fixes and your game would be even more awesome!
