Thanks a lot for your feedback! :)
Yes, we require some feedback on the level/game progression. Maybe some environmental details which show some direction or distinction of different areas in the level? Leave your ideas in the google survey or just here in the comments. Would you prefer a more subtle representation of the progression, a more mechanical one, like find a key and then a door? Or would you prefer a map?
About the music, the game has a more disney-ish thematic, like Tom and Jerry, so we did not consider that it might be perceived as grim.
Maybe we gonna dig more into the grim theme? Sounds a very interesting way of evolving our game too :)
Thanks a lot for playing!
