I remember playing this in the early 90s from a shareware cd, but even then I didn’t really think much of it. Compared to platformers on consoles, even older ones from the NES, it just seemed like it wasn’t on the same level somehow. A lot of that might have to do with the horrible experience of trying to play it on a keyboard, though.

Low res textures that would get resized with a bilinear filter, as opposed to the PS1 which used no filtering, resulting in a sharp but pixelated look.
