Machine-shooting game from the 80s

Gameplay: Mainly shoot, jump, collect items (invulnerability us.sw), upgrade weapon and shoot again.

You begin by selecting a character and plays a short tutorial.
Will run from left to right - the screen scrolls with. Shot automatically - only the direction has to be determined, but this takes some practice because of the spongy and control during the game often makes for frustration.
By collecting power-ups you can temporarily improve his chances of survival. Unfortunately, through in-game purchases, but what I have not yet used.
The degree of difficulty increases rapidly and from level to level to get it with more and more enemies to do.
A typical machine - shooting game of yesteryear - fast and hard.

Conclusion: Contra-evolution is very reminiscent of the original Nintendo Game of the late '80s, but unfortunately the spongy control ruining the fun.
Running on my Galaxy Note 8 without problems.
