★★★★★

Adnin Firdaus

Not bad. For a simple game. But after 5th stage, difficulty spike. gonna have to farm.

★★★★

Morice Amadeus

The game is really addictive. Lots of upgrades and cool weapons. I am not happy with the ads when you try to claim extra things. I would like to see in the future more weapons and different stage settings.

★★★

Oliver

There is SO much RNG involved on whether you win or lose. You have no control over target priorities (other than boss) and I have seen many attacks (railgun, radiation link, laser) after a lone ship instead of hitting a group. There is no way to disable cards to improve the odds of you getting what you want. The prices for things are insane. 2 Stars for the visuals and 1 for the potential that this game becomes great.

★★

Anthony Duong

Look at all the newest reviews that have more than 2 sentences will let you know what you're getting into. Very fun game for the first 10 levels or so, then it becomes either a pay to win, or grinding for over a week to advance. Even if you didn't have to pay for 2x speed, it takes way too long to move up a level. Rewards for the long ads are really bad as well.

x2 speed is behind a $10/month or $50/life pay wall. In the beginning, you make good progress until you get close to level 20. That's when the paywall hits hardest. You can not effectively progress at that point, even changing your loadouts to optimize damage against enemies' weaknesses. The ads are expected, but some seem like they never stop. I even bought items from the shop with on-game gold just to have them not show. The game starts great, then falls off a cliff quickly. Just don't
