The artwork is nice and simple, and the gameplay is quite challenging. The mechanic reminds me of a smartphone game about driving your motorbike on a busy road and pass the other cars really close to score points.

Nice work! there was an issue with the sizing (i also had a similar issue in my game XD) -- cant see the boundaries.  Also, had no idea that we can shoot! maybe put some in-game UI (somethign that I also forgot to do for my game lol)

Finally, I think maybe remove the 'exit' button on the end screen -- cant really 'exit' in webGL.

Game play sets a good mood but it's a little confusing how you get points and bullets for going near a rocket but no points if you make rockets collide into each other.  

For anyone playing caution: Full screen didn't show any of the (non-essential) counters at the top.

Your game is very challenging.  I can not guess what direction the rocket  come in. I like your art work it look simple and  unique.  How to make  score 37 OMG!!! My best score is 10 lol

This one was fun, did you baase it off any specific game?
