Finally I was able to go to the boss level but I couldn't last long. I played the game for more than 2 hours but I could go to this boss level only 2 times. You can say this game is a test of patience. Why did I say this?
The game is quite fun at first and it is fun to play but as the level progresses, when the green balls start to divide and their speed increases, then the survival becomes a challenging matter because the small fire cannon cannot be fired non-stop. It can fire up to a certain level, after which it has to rest for some time and then it starts firing again.
In the first level, it is not that important because you will not pay attention to this but as you level up, you have to save the fire cannon from the green balls, rest it again to fire, fire the green balls as well. You have to do all these tasks at once.
And the most interesting thing is that the amount of health tokens in this game is very low. I mean, at the beginning of the game you will get 3 health tokens but when the green balls are split then you get some health tokens from there but that is very less and it makes this game more challenging because when 8-10 green balls are jumping on your skin at the same time then it is quite tough to save the health of the fire cannon from the empty space and that is why I was able to go to the boss level only 2 times after playing 2 events.
But as soon as the game was over I kept thinking that if I had played a little more calmly then I could have gone to a higher level. ...Anyway if any of you have played the game please give your opinion and tell me which level you were able to go to.
Keep playing and have fun.
