Hi everyone,
I have spent some time developing a prototype puzzle game that I intend to eventually release as a finalized product (with additional worlds, levels within worlds, a nice story, etc..).
In this cat puzzle game you have to trace a route over a 7x5 grid for two cats to make them arrive home. On the route, each cat interacts automatically and differently with the elements laid in the grid.

Before I continue further with the development I would like to gather some feedback as to see if I need to steer a bit the project. I am aware the graphical aspect is very raw and a loot of feedback (game to player) and quality of life features need to be implemented. But this was not my priority at this stage.
I am mainly concerned about the main mechanics of the game. Things like:
Is it fun / could be fun (if improved)?
Is it challenging?
Would it scale well (like 100 levels)?
Would you considering adding additional mechanics (I had also considered cats abilities could be represented by cards and the players could try to switch those cards from one cat to the other).
Any feedback is welcome :)
