This game is quite fun to play. A few things to really take care of to make this game super interesting are
1. it's taking a really long time to load up the waves.
2. Very confusing on the Game Elements, for example, why the two houses are there.
3. As there are no sounds in the game, it feels really odd.
4. Also, sometimes the game gets stuck at one point of time.
5. As the following mechanics of the zombies are all the same, they look really odd while following the player.
6. You can possibly add up more power-ups, guns, and other such elements to the game to make this game more action-packed and challenging.
