I first saw your game on newgrounds. It's a very good shmup, nice job. And you made a good use of Larzes's assets 👍
It works very well on both my laptop and my smartphone.
Yass and now phaser 3 is even more amazing on mobile ... maybe I'll find the time for a 2nd one but Lazer keeps selling his assets as 1 huge AI image ... it takes a lot to setup meshes or try to cut out individual parts for animation. That's really the only bummer... also if you're also an HTML5 game dev I hole heartedly recommend the phaser editor. Makes boiler plating and setting hit zones so much easier than through code.
