Nice graphics! I included it in my LowRezJam compilation, if you’d like to take a look :)

I liked the overall look.

The timer is pretty punishing.

Controls are... rather stiff. It's super hard to aim and I am not really fond of how quickly the health bar is going down. Especially since you take a while to reach an enemy.
also, super hard and tricky to aim at enemies.
But the graphics are nice and i like what it does when you explode a ship!

The flying animation is a little choppy; might help to have positions to slowly ramp to depending on what keys are held.

And since figuring out how to aim is tricky, maybe a reticule could help? Not a GUI one, but, like, just a flying object at an in-between point for accuracy.

The gameplay felt like blowing up giant gas cans, though! ^-^ That was fun!

It takes a bit to get used to aiming at the targets, but once you do the game is pretty fun. The visuals and audio are both fairly simple, but they work well. I like the explosion when you hit an enemy. The main thing that sours it is that the energy bar thing doesn't adhere to the 64x64 screen.
