Only 70 Time Tunnels were produced due to copyright issues over the TV series. Much of the game's logic was adapted to Space Time but with an altered layout and features.
VPX history: roth and I did Space Time back in 2018 and adapted it to Time Tunnel shortly after. Resources were pretty scarce but it turned out ok. Then last year brad1x PMed me with a brand new redraw of the game art. New art deserves new rendered textures, physics, sounds and VR support, so now you have version 2.0. Thanks to leojreimroc for the VR room.
