This game is pretty polished and has a neat concept. I think how the critters interact with each other is pretty adorable. There’s a cool effect over the food when winning too, which feels great. Some of the level design like the positioning of the fences should be improved, because it can be hard to maneuver once the critter is being controlled. Also, because the only reason to control a critter is to move it away or closer to its food, I feel that it becomes tedious after a while and is not enough to engage the player over many levels. If that’s the case, moving critters with the mouse would have been the better control choice. So to counter this problem, it needs more mechanics that motivate the player to possess. You can try allowing the player to gain the critter’s abilities, essentially becoming a more powerful version of that critter, like maybe the player can pounce and scratch as a cat. You can also try varying up the gameplay and not make it all about defense. Lastly, there are some AI behavior issues where the cat sometimes doesn’t hit the mouse, or the mouse doesn’t eat the cheese.
Overall, I enjoyed trying to defend my steak and cheese and had fun watching the little critters move around. Good job!
