Overall I found it fun to play, I only had issue with shooting. I needed a lot of time to get to the point where you can shoot and jump. 

I would advice you to  keep this difficulty but to either more indicators on what is happening with reloading (I get you kind of did that with avatar becoming white) . You can make it more obvious with color shift. 

Liked it.

Really enjoyed the idea  of it, and it's definitely on the hard side. Wound up going quite a ways by just shooting constantly down, so I was pushed to the top of the screen. It was fun.

I really like the idea of shooting acting as both an action to get rid of enemies and a movement option. Doing this in an endless runner where you are constantly on move makes this more interesting since you have to gauge whether the points are worth using your shot or else you'll die for being greedy. However, since the platforms are randomly generated, it does create some scenarios where its impossible to shoot the alien and make it across the gaps. Still nice job.

Nice! Cool movement, although maybe hardtiming the shots maybe isnt the best, I still enjoyed it. Got a score of 9.

Interesting game. It would have been nice to have a bar that indicates the cooldown of the gun. Got a score of 8.

cool idea to make runner with shooter

the only problem for me is control, i dont like this kind of control and i see it on few game but i dont juge realy this.

so gg for the game :)
