This is the original 1993, VGA, MS-DOS version of Day of the Tentacle, with graphics presented at a fairly low-resolution 320 x 200. They still look great to me though.
Compare this to the high def Double Fine remake of 2018 and there is no contest – the high def version wins every time – although there is still a perverse nostalgic thrill to be had from playing the original VGA version.
