Dave by John Romero is a well designed game. It grips you with it's interesting levels, which seem impossible a the very first attempt. The level 4 is especially hard. Harder as it progresses. I needed a throughout video for guidance. Still you will need the exact timing of the keys and controls to pervade further. The warp zones are surprising to me as I was aware of only 10 levels. It retained the curiosity in me about further attempting them. This too took me 30 thirty years to complete it just like POP 1998. Finally it's a game that I recommend to any game fans out there. Gradually it's at the classic status for its user friendliness and technical content. This is still my pastime game in my leisure.
