Zamrium is weak, ha

Actually, it's not a pretty bad game. If you know how to disable the ads( you know, no wifi), then it's a cool game. The patterns are decent and I like the music, though there should be more boss themes. One thing though is that there are a lot of bugs.
Like, if you play and exit out of the game over and over, it will cause your game to crash, all levels apply.
What happened to me is that after it crashed, I couldn't open the level for a while. When it did become playable again, the lives had reset to 0.
Also sometimes after it crashes and it's fine to open again afterwards, you get a huge amount of lives, but playing through with those lives will make it crash.
Besides that, the game is decent and makes a fine bullet hell.
Also I think that Kang-mu, the third boss, is harder to beat than Pu-Ang-Ma-Lai, the forth boss, somehow.

Fix ad problem

This game is amazing, I love it so much and think it deserves a 5 star review. However, I think the main reason this game has a bad rating is because of ads. They block the information on top of the screen, which makes it SO confusing. Other than that, great game.

Ad placement is awful

I am COMPLETELY fine with ads, so long as they don't completely interrupt the game. ALL vital stats are hidden, AND YOU CAN'T BACK OUT OF THE TUTORIAL BECAUSE AN AD IS OVER THE BACK BUTTON. If the screen was shrunk to accommodate it, thats fine. If you could even pay for an ad free version I WOULD. But to just interrupt gameplay with an ad that blocks everything, that is unacceptable.

Hasn't been updated in a while

Slapped the ADs on and didn't look back. What was good and could of been expanded to greatness has been a let down.

Love It!

Game is freaking awesome an I just love how insanely hard some levels are

Remember just turn off wifi to turn off ads
