This was fun. The warning indicators are a really nice touch. I would recommend adding a sound que to go along side them, to make sure they are understood better. My one question, is that the player seems to have a weapon but its not used at all. If the game was intended to have a shooter like mechanic then I think you could work to make that fully realized but if not, I say alter the spite so that it doesn't give the player the impression that you can attack.

Excellent Graphics choices giving a good contrast to the usual jetpack looking items

The visuals are good. I like the fact that there is a warning when there is a missile coming. I was still able to collect coins after I died. The controls felt fine to me, but gravity could be a little better.  This is a great job.

To rephrase what everyone else is already saying, the visuals look great. However, I found it hard to control and lacking any real difficulty. About 90 percent of the time, I found myself hugging the floor and tapping the spacebar to avoid any missiles that would lazily come at me. In the 10 percent of the time that I was airborne, I thought the jetpack was a bit overtuned, and that gravity was a bit too low. Consider reducing the power of the jetpack and increasing the power of gravity.

Graphics and game feel felt great. Good work!

The gameplay felt nice, only little thing other than what was already mentioned is that I think the player's hurtbox should be a bit smaller, I died a few times by just being close to an obstacle. But overall great clone

I liked the visuals of the background, and the foreground sprites were probably fine, but it did feel a little odd having a very detailed background and more pixelated foreground sprites. I feel like having sound would have improved the experience.

I felt that the controls were a bit floaty.

The pause button on the upper right is bugged. If you press it, it will continue pausing/unpausing in intervals. Also, coins continue scrolling, and the player character continues animating while paused. Also, things keep scrolling after you die.

As I've said on some others, regarding accessibility this game would be fully mobile friendly if you had also accepted the mouse button as input.

Gameplay wise it was good. Had two types of obstacles, coins, and score (though not saved between sessions.)

Super cool, and I agree with Ezreem. Visuals look realy good and it feels like there could be a whole game behind it. Sounds make such a big impact even if just a few ones, really hoped for that. 

The visuals are screaming that they want to tell some kind of story — shame the game ended up mute, it really could've used some sound. The animations are cool, especially the walking one. The background is mesmerizing.
