This game reminds me of a 1980s game called Thrust, saw it and thought got to get this.
It is exactly how I remember Thrust back in the day.

I read a user comment who said it goes from ok to too difficult. I agree.
I am on the 5th level (I think) and you start off with guns on the side then drop down
to a cavern on your right. There are way too many guns shooting so your best bet is to shoot at the walls hoping the rebounds go in line of guns and destroy them. Even so you have to stay hoovering away from the walls which at start are very narrow, then just when you get through you have even more guns shooting at you but there are too many enemy bullets passing and rebounding off the walls just waiting to get you from behind (sort of).
I have spent way too long on this level so its just got me where I leave the game and come back a few days later.
It feels like the levels went from 1 to 100!

Still a good game but just too difficult too quick, it makes you feel totally defeated instantly into the game.
Still I`m going buy the 2nd one anyway.
