This is a really lovely game with quite challenging puzzles that are not too difficult to make you feel frustrated and not too easy to not make you think out the box. I liked a lot this balance of difficulty and the way it made me think in a different way and perspective.
The music is very calming and relaxing, it's perfect for this kind of games and puzzles where concentration and a state of relaxed mind is required to focus better in order to find the best solution that might not be the same for all. The minimalist style of the pixel art combined with few colours help to create this little mesmerizing and relaxing environment. The background and design of levels don't distract the player from focusing on the main goal: saving all 20 cats.
I also noticed that the titles revealed a small hint in the approach and/or solution of the game, nice detail. I liked it. Both a title of a level and a hint. The tutorial was a bit strange with the change of keys to move wires but the "problem" was easily overcome by simply playing.
In the first level, where I had to jump freeze in order to move wires and then advance in the level, was a bit challenging at first but once I discovered I just had to jump and stop at the right moment in the right place other levels became more manageable but errors and trials played a role to help me advance each level.
Congratulations for making this game in 48 hours and getting frontpaged, well deserved. And yes, kittens are adorable!
