PRELOADER
Pre-loaders are very important. This is a big file, 24.6mb, and one too big for me too immediately stream. It's annoying having to constantly pause and play and restart because i don't know how much has loaded.
That being said you have something really good here, the art style is REALLY nice and enjoyably detailed. The comedy was nice, but the music made me thing it would be something a little more serious, i think voice acting and sound effects would have set a better tone for comedic moments, and the song could have begun along with the mouse parts.
The story and concept were super cool and the dark and murky world you created was engaging. Shame it was pretty much all tweens, but i suppose thats all that art style really allows for.
