Love that the game had an alien theme included! So fun! The twists were really good. Loved the dynamic gameplay from stage to stage. I think the alien level could have used maybe a little more variety within it though. I found myself holding down the shoot button and walking back and forth dodging the bullets fairly effectively. If some platforming was brought in too that would make for a decent challenge with all the aliens shooting at you. Also, the music was a bit loud, not sure if that was a WebGL thing, I've been noticing that in some WebGL games specifically. Might be something to look into. Overall though, really great game!
