Great stuff, I really like how this feels to just move around in. The art is also amazing.
Some feedback I have for you :
I think this would benefit from a way how far you are to completing it. I mentioned this in the stream but just to reiterate. Maybe instead of a timer it could use destroying targets as a completion condition also. That would encourage attacking enemies while also focus on dodging, just an idea tho.
Another thing is that there is not really a reason to use the normal shooting mechanic. If you just want to get rid of enemies quickly missiles are always the better option.
I like the idea of having to barrel roll to loose missiles. But the UI for those is pretty cluttered and it's hard to tell what's happening sometimes.
Hope that helps if you want to continue developing this .
Great game.
