Pretty good, however there's only 11 levels, the last being an infinite survival level. With the lack of overall content I fear the game loses its fun. I actually spent the time and farmed maples, unlocking ships. I was hopeful with the pacman ship as it advertised new content. Sadly, it was only skin changes. I would recommend trying, but I wouldn't spend money on it. There are also ALOT of ads.

super cool game! the only downside is that there are so many ads that it makes it so frustrating to play. to open a level, even if it's one you've beaten, you have to watch an ad. to get your other life (you only get two, which sucks), you have to watch an ad. yes, they are only max 30 seconds, but still super frustrating that the only way to skip the ads is to buy coins or have enough from playing the levels, which again, require you to watch ads. otherwise a pretty cool game!

Absolutely love it. THIS is how you redesign a classic game for mobile. 100% Free-to-Play, intuitive controls, good graphics, and don't get me started on how much I love the auto-pause function. There are in game ads but they are minimal and can be removed by a single IAP. There's no energy system so you can play as much as you want and revives/continue can quickly and easily be earned in game. Keep up the good work!

很好玩， 希望能够出更多战机੭ ᐕ)੭*⁾⁾
