I was not expecting to see Sinistar mentioned, that's one of my favorite arcade games! The ship movement and shooting definitely does remind my of that game and I like that you even added the wrap around for the level. Like someone else said, I think the fuel and size of the map doesn't make as much sense for this game since the objectives are so close and the fuel is consumed so slowly but I could see them mattering more if you wanted to expand this into a retro space sim like the old Star Trek games for the Commodore 64. Nice work!
