Uncaged is a good rhythm-based game with simple controls. I think the best part is how satisfying the game feels. The feedback you get from landing a punch feels really good.
However, I do have two small complaints about the game. My main issue comes with clarity. When you get hit, there really isn't much visual indication other than one of your hearts going missing. Additionally, at higher speeds, it gets kinda hard to tell which characters are on which rows. I think if the camera was a bit higher up and tilted a bit downward, it would give a better perspective and allow players to time their punches better.
I also think that the game is a bit too simplistic in terms of controls. Adding in a possible "holding" mechanic where the players have to hold one of the buttons and release at the right time might work. Another idea could be to fill a "Fever" bar and if you hit a certain amount of enemies in a row, it would grant a period where you could go wild with your punches without any drawbacks, just to add to the satisfaction of throwing punches wildly.
Still, I really like the idea of this game. It's very easy to get sucked into trying to do better with each playthrough. Overall, it's a solid game!
