This game is actually a port of the 1981 Namco game Warp & Warp. I am wondering if this should be considered different, because the game and level design definitely is.

It is indeed almost the same system.

However, "Warp & Warp" is an arcade game and it seems a bit strange to mix it up as a page from Warpman and SRC, which was released as NES.
Therefore, I think it is better to separate them.

Nowadays, we can play it in arcade archives, so it is a good time.
