Cons:

• Short playtime. Game was finished to almost 100% completion in around 3-4 hours.
  
• Somewhat awkward (keyboard) controls. Z is bound to jump like in most platformers, but A is bound to attack, and X for special abilities. With a controller it isn't as much of an issue.
  
• Repetetiveness. You fight the same boss multiple times over, the only difference being a new color, additional attack stages, and higher health. The difficulty curve makes up for it though.

Pros:

• Perfect difficulty curve. Game difficulty and complexity increases as the game goes on, as you constantly get new tools to help you progress and must learn how to use them.
  
• Customizability. You can customize your weapon the whole way through, tweaking it and fine tuning it to meet your needs using points you gain along the way.
  
• Great graphics. The blur in focus when switching between dimensions really pulls you into the game. Movement is very smooth on the eyes. Even all of the sudden movements from special actions in the game transition very smoothly.
  
• Secrets. There are hidden health and gun upgrades all over the place, if you can just find them. If you're a completionist like me, try to find them all and get a 100% save. Heck, 100% three save files for bragging rights!
  
• Replayabillity. Because it was on the shorter side, starting up a new game and getting into it isn't a challenge. Plus, because of the customizabililty with weapons, you can try a new playstyle every game. Or, just challenge yourself to only use certain weapon upgrades throughout the whole game, or none at all!

Summary:
-= 8/10 =-

I wouldn't pay the full $10 for it because of how short it was, but for 99₵, this game is a must buy.

Have some change left in your wallet? Looking for a fun game with a Metroid feel? Get this game. It won't dissapoint you.
