    The monetization aspect of the game has received overwhelmingly negative feedback from users, primarily due to the excessive number of ads. Players report being bombarded with ads after nearly every level, often spending more time watching ads than actually playing the game. Many users express frustration over the lack of an option to pay for an ad-free experience, with some suggesting that the game feels more like an advertisement platform than a playable game. While some players acknowledge the necessity of ads in free games, the sheer volume and frequency of ads in this game have led to a significant number of uninstalls and low ratings.

    • “Man, I love this game! Simple, straight to the point, no ads, good graphics, and basic. I love how it keeps getting difficult and more challenging, and how you can unlock more characters, each with their own special skin and weapon. The latest zombie mode looks fascinating and very well done, with so many rounds and you can receive a lot of rewards by simply playing 10 rounds, which is about 20 minutes. You can also unlock Venom, which is my favorite skin; it is underrated!”
    • “This game is super cool, and I even have it on my dad's phone. There is a problem when I am done with the level; there are ads, but the game is pretty good.”
    • “I like this game because there are no ads and it's not laggy.”
    • “The sheer number of ads in this game is ridiculous.”
    • “More importantly though, after every level is an advertisement and levels only take 15 seconds or so to clear, so you are literally watching ads more than you are actually playing the game.”
    • “You spend more time watching ads than playing the game, which is unfortunate because the gameplay isn't too bad.”

Users frequently mention that the missions feel repetitive and disconnected, lacking a cohesive plot or character development, which diminishes the overall experience. Additionally, the overwhelming presence of ads detracts from the enjoyment of the gameplay, further emphasizing the need for a more compelling narrative to keep players invested.

    • “It would also be cool if there's a chance some missions will have challenges applied to them such as not being allowed to be seen.”
    • “The game is good and fun... maybe if the devs added a story, or a reason you're killing these guys, it would be better.”
    • “I love this game because you can hide and kill all the people, but I wish they would make a story about our sister or our mother being captured by the final boss.”

    • “The missions go nowhere, and the special missions are locked because you don't have the hero while you're trying to unlock in order to get a hero.”
    • “After 4 or 5 missions, everything becomes boring and repetitive.”

However, the frequent ads detract from the experience, leading to frustration that overshadows the initial humor. Overall, while the game has a comedic charm, the excessive advertising significantly impacts its enjoyment.

    • “Plus it's too repetitive; at some point, it's not funny anymore.”
    • “The game is good, but the advertisements are so annoying. The creator purposely placed the advertisement container at the bottom side while playing, which always leads to accidental clicks on the ads, making the game not funny anymore.”
  • music34 mentions

    The music aspect of the game has received mixed reviews, with many players expressing frustration over the overwhelming presence of ads that disrupt their listening experience, often pausing any background music.

Overall, players believe that improving the music and sound design would significantly elevate the gaming experience.

  • optimization19 mentions

    The game's optimization has received significant criticism, with users reporting severe performance issues, including slow loading times, unresponsive controls, and frequent crashes, particularly on higher-end devices like the Galaxy S20 Ultra. Many players feel that the focus on ad revenue detracts from the overall quality and performance, leading to a frustrating gaming experience. However, some users noted that the game runs smoothly on low-end devices, suggesting inconsistent optimization across different platforms.

    • “I paid three bucks for a week without ads and would have enjoyed it for that time, except the game is also nightmarishly optimized; it stayed chugging a few levels later and was unplayable.”
    • “Too much delay with the control stick; the game performance still needs a lot of work.”

Overall, while some enjoy the game, the grinding mechanics are seen as a significant drawback.
