I like the experience of killing the enemy. It feels so satisfying. At first I was like, what? the bullet doesn't work! hmm.. Let me press and hold it. Then boom, an options where I could expand the balloon and shoot them upwards. Cool! But then I was like, what if I just continue to blow the balloon until it fills the majority of the screen. Boom! It obliterates every enemies and the UFO. That feels soo good lol. I like this game. Very simple, tight, and fun to play. Good job! I like the way you design your game.
Too bad It caps me to play only up to Level 4.
