I know you aren't the best English speaker, so if you want I could use the translator to edit this post, so here goes:
Let's start with what I don't like, then what I do.
Cons: The opening of the game is a bit annoying because of how many ellipses you use (...) it makes the text scroll strangely. The controls in the tutorial don't work for me, (Jumping is "S", Shooting is "A" and Dashing is "D") other than that I see nothing wrong with it. There are a few technical problems, with the gameplay, such as it can be easily exploited and the shots coming at you are usually unavoidable which can get annoying and unfair. And that's pretty much it for the cons. (But there's still grammar of course, but I won't hold that against you)
Pros: The music is really cool, and the concept is very original. The game is also very addicting, even though I died A LOT, I for some reason wanted to continually play it. I had a lot of fun with the game and did make it to the end, so good job with this, it's a very nice change in pace than with most games made with VX. I hope you continue to build the game, sir.
