REPO game features diverse monsters with varying difficulty

The game REPO features monsters that players encounter while collecting valuables. These creatures vary in difficulty and appear randomly on each level, requiring players to learn their behaviors to survive. Killing monsters yields orbs worth in-game money, adding a risk/reward element. Level one monsters, like the Peeper and Shadow Child, are easier to deal with and cause less damage. Level two monsters, such as the Rugrat and Chef, start appearing on level three and are more challenging, often requiring strength upgrades or multiple players to defeat. Level three monsters are the hardest, including the Headman, Reaper, and the powerful Trudge. These monsters have high health and can quickly kill players or damage loot, making them difficult to defeat and sometimes best avoided.
