Rex Rocket

Challenging, fun, simple story, responsive controls, a fun mechanic for transport with a decent learning curve (shooting down = vertical lift), wall jumping, a load of different weapons, a tough final boss.

If you're ok (or happy) with extremely high difficulty, and willing to overlook the complicated jumping controls, I'd highly recommend this game.

The sprites and backgrounds really pop and there are some interesting lighting effects done with Rex and other sprites.

Others praise the fact that it is a Metroidvania, despite the fact it is as linear as Metroid Fusion, which I did enjoy due to the bosses, story, and atmosphere.

The rhythmic movements of the setting around you is complimented perfectly by the outstanding chiptune soundtrack provided by musician Saskrotch which, just like the game, strikes that Megaman style all too well specifically of the 1-3 era.

You got variety of sub weapons which all are useful (except for the rocket launcher), and you'll use them a lot to beat a certain sections.
