    First off, this is a great game. what I like is there is not one forced ad. But honestly, I like the challenge. If your trying to progress quickly, well thats a different story. And you do have to repeat levels to build up stats to progress. I dont mind taking my time. But here is a tip. when you start, dont worry about trying to clear the level perfect. After several levels, go back to level one and play foward. You will easily beat the level and get all trophies for that level. Repeat.

    The game is challenging but can still be fun. But, the RNG of it makes it more annoying sometimes. Mainly when it does not give you the type of defender ship you want. And the fact that you have to grind A LOT, that is if you do not want to pay, to get special win conditions or just beat a level can make it a bit repetitive and boring sometimes.

    Enjoying the game so far. Except for the apparent Play Store Policy violations regarding the ad network associated with in-game rewards in exchange for time spent watching an advertisement. The current network used forced redirect loops (to within the play store) which can easily see system RAM dump the game, resulting in no reward (as the game will perform a fresh launch.) Game deserves greater than 3 stars; stealing my time (30 seconds at a go) doesn't agree.

    The game's fun for awhile. The force field ability never goes where i need it to though. It always goes where the least amount of ships are while I'm getting absolutely bombarded on another side. It would benefit from like a drag and place mechanic. The laser will attach to a big x10 ship for it's entire duration while alllllllll the other ships are shooting me. Like why is it not constantly shooting at all the other ships and just focuses on the one big ship while I die? Super annoying

    The game is fun-enough until you hit an abrupt progression wall. From there you'll spend days to weeks of reattempting the same levels without getting any better results and without being able to complete the levels you may be stuck on. This will be the case even with watching loads of ads to get more materials, get more unlocks during levels etc. The fun practically dissipates at that point.
