Not having much luck am I
- About 10-15 years ago I remember playing a 3d space shooter games.
I think it was on windows 95.
It was arcade style - you looked behind your ship, moved it around the screen with your mouse and slowly waves of aliens would come and you had to shoot (mouse click) them while they moved around. If you couldn't hit them in time, they would fly towards you and if made contact with your ship you would die.
After a while you could get upgrades and then you would fight bosses. One of the upgrades is a bomb and when you right clicked it blew everything up on screen.
There was also this really rare powerup that I think I got once, which makes your ship spin round really quickly and send bullets everywhere for about 20 seconds, destroying everything.
The most striking search item I can think of is that after I few levels (I think level 2 but unsure) the game actually switches from being 3d to on it's side and the waves would come from the right in vertical lines.
There was no music from what I remember but the sound effects were quite eerie. The aliens would make all these strange sounds, and there was this computational style narrator who would say things if you got a powerup (Thing's like "power increased" but I don't remember exactly what he said).
I spent about an hour searching before I came here, and the closest picture to describe it is here - http://badgerheadgames.com/wp-content/uploads/2014/04/tapinvasionl6.png
Although it was much better graphics (as it was 3d) and there was nothing at the bottom (except your ship)
The game did have a score system and was very difficult (probably due to the 3d aspect), I never beat it nor got close.
