A good quick top-down shooter. I like the sprites, and tiles, and interesting that it seems the bullets travel faster if you leave them for a bit, and it turns into a different little micro-mechanic to try and dodge your own bullets so you can just draw the enemies into the path without having to shoot.
The bullets do seem to get stuck on each other if you shoot two in the same direction from the same spot. Could use some music and sound fx, but well done :)
