I really liked the art. It is a bit repetitive when you look specifically the way the background elements are scrolling, but it is beautiful. Music is nice, but sound effects are way too low in comparison: it's hard to hear when the narrator is giving a hint. I think I'm bad at this type of game that requires timing, but the difficulty curve looks okay. I just don't like the way the enemies can get back to you from behind, I think this specific design choice is not helping the game. Game isn't very innovative but it is fun even if it's going harder the more you go, which seems to be normal to me. I'm just not sure about the theme here.
That's still a good submission for a 7 days jam, good job guys.
