Hello,
I remember I played it on monochrome CRT in DOS. I`m sure that in this game you played in the same point of view as in SR, also in the space but you started game in the outside of the tub. After you played game was dynamical changing scenery to flat road, next going into tube. Everything was so smooth. You just had to avoid bigger blocks, maybe jump - I`m not sure. If anyone can help me with the title or send me site with simmilar games list for DOS I`ve be glad.
