This is probably a long shot since I remember so little about it. I played it on an arcade machine in a bar, not sure how long ago... probably around 10 years or so. Anyway, it was a side scrolling SHMUP similar to R-Type, but I remember the graphics being far more colourful than most other games (perhaps it was just that level though), the scenery seemed to be made up of lots of brightly-coloured spheres and I think the enemies may have been made of spheres too. It had 2 player co-op. I've been struggling to remember it for so long now I've almost given up hope... scoured SHMUP websites and found no clues at all Any ideas?
I've played that to now that i think of it... the name is on the tip of my tongue!!!! urrrgggg ill post if i remember hmmmmmm
