Thank you for trying out my game, and thanks for the feedback. Yeah I know there's quite a few bugs like that, I unfortunately lost my final patch when my computer crashed which caused many of them to reoccur, and the due date was close on the horizon :). Yeah with further development I'd add more puzzles, add some more verticality, and if possible get some actual modelers and/or animators to help make assets (especially the cat) so that I could focus on improving the gameplay.
Early in the development process I made a mistake by choosing to use Unity's inbuilt physics system, which was very hard to handle, and in hindsight I wish I had manually controlled the numbats location and rotation at all times.
