Neat arcade shooter. I would have liked if at least for when they disappear, they had a short animation instead of just instantly being gone. Also, some more variation in enemy behavior would be a nice addition, if you plan on making a post jam update, like one that walks sideways before attacking or something like that. Music and sound were good. Also, you should reimport your textures with the 2D pixels preset, it doesn't look good with this blurring, otherwise the graphics are nice.
