Such a nice little concept. The music, worlddesign and especially the artstyle sold the idea of a sneaky little mouse (ratatouille vibes). The character design especially were very nice.
In terms of level design:
At times i had some difficulties finding my way around the level, (only to discover at the end i zoom out haha), epescially when making certain jumps; leading me to have some difficulties on where to go. Some signposting could greatly help this (If you look at the platforming sections of Doom (2016) they put green lights on each thing you need to jump, clamber and climb onto. Or Mirror's Edge where anything interactible is made a bright yellow, red or blue color. Or you could something more subtle).
Lastly, the layout of the level (and how i progressed through it) was slightly confusing, perhaps you can look at how other games structure this (completely linear, a central hub with different sections, something in between, etc).
I do like how the different set pieces (balls of wool, swinging lamp, and pushable broom) fed into the gameplay, that was nicely done.
All-in-all, very nice :D
