I really enjoyed your game, but there are a couple things that I didn't like!
One of them is the tutorial and that's because of the enemies constantly shooting at you. I couldn't really read the dialogue because of that, but it wasn't that bad.
Another thing is the movement, it's just a little bit hard to get used to it, it really feels like you are not really in control of the character sometimes, but maybe that just me.
I really felt bullied in this game, the enemies are pretty hard to kill, that's not a bad thing btw. The rockets were very annoying, again not a bad thing. I didn't finish the boss because it was to hard for me :) but it was a nice boss.
The sounds are nice, but at first they earraped me.
Well the graphics were nice, the menus were simple nothing special really, but they worked fine so yeah, that's what matters.
I can see that you are a big Dani fan, you can see that in this game, it looks very similar with some of his games and again that's not bad, well I think you should find your own style, or if you like this style keep doing it, cause it's nice and you're doing a nice job with it.
Well that's it, one more thing, try to play around with more styles of games and find your favourite. So yeah, great job and keep up the good work!! :D
