6 stars is impossible!!
I got through the first parts of the game, and finally got to what is probably the final room. But when you fire 6 stars at a time, no star gets fired straight ahead!! In other words, it is IMPOSSIBLE to kill the 10 creatures that come at you together because you have no protection directly in front of you! That big weakness in the game was very annoying, since it takes ages to work out how to enter the final room, and once you get there it's impossible to win.
Right then, as for a real review of the game, I think that everyone who says "the graphics are terrible" just hasn't got into the game yet. If you give the game a chance, and get over the fact that the graphics/movement/sounds aren't brilliant, you find it's a fun little puzzle to solve.
BUT FIX THE 6 STAR BUG!
