Thankyou, Killerwatt reminded me of a variation of Defender type game. I always thought the C64 game looked too simplistic (flat colours/lines) compared to the other games available, just wasn't sure if it used a different technique (eg drawing lines/vector shapes) over a tile based system.
Suggesting other games that you might prefer on our CPC's is great already looked at Trap and Phobia (thanks ||C|-|E|| and TMR, might try see if there is a thread about that here or start a new one (please point me in the direction if there is one you know of).
While I work away on other projects for CPC (The Last UFO) for example I am really keen on knowing what people might like on our platform that never got published for whatever reason?
If anyone has a suggestion what a potential CPC game of another non CPC game would look like, I may be inclined to play around with some ideas.
