Hi, I'm one of the developers, sorry to reply so late.
We take note of your comments and the bugs you experienced, as well as the confusing or non-existent menus.
We have already solved the menu issues you point out, we will add all the video features to this itch demo in the future, the needs tab has been redesigned, the food store shows treats on one side and food on the other when clicking on a bowl and it might be confusing for players, you are right, and the missions have been redesigned and are on the way to be clearer, like the maze you mention that refers to the mini-game.
Overall, we will update the demo to a more stable and finished version of the game, limited to the demo content but playable.
I'm sorry for your experience a few months ago while playing the game. We will work on it, thanks for your effort in playing our game and explaining your experience <3.
