This is one of those games which certainly didn't pass the test of time, mainly due to the fact that even if anyone is interested in it nowadays (which is highly unlikely), it's pretty much impossible to run it on any modern system properly, if at all.
Still, the Toy Story franchise has won a great success over the years (speaking of the movies of course, not the video games) and as a big fan of it myself, I personally will always have a warm place in my heart for this somewhat flawed and rather ancient game.
It's not like Toy Story is too bad, but, it's main flow is that instead of being insanely good it is mostly insanely difficult. And not in a fun way. While being a simple platformer, and even though the game itself isn't too long, the very few tries and hit-points you'd get for each game will require you to master the levels in a way which is, as I said, not fun. It can get rather frustrating and tiresome after a while, not to talk about time-consuming.
What's good about it then?
Well, it's Toy Story of course. The beloved characters are there. For being a port of Snes game the graphics are serviceable, like the rest of the technical aspects. The levels are varied and the gameplay slightly varies with each one, which makes things interesting.
Of course, there's not much reason for anyone to be too interested in this game, especially not in 2015. This review is for the loyal fans which also happen to like decent video games based on their favorite childhood animation films.
This game is alright. With some patient you can handle it. Or with cheating.
And some technical knowledge, because to actually play this game you need to either have some old PC running Windows 95 (Does that even exist?), or to emulate the game on a virtual machine or the Snes\Megadrive emulators (which is easier and isn't too complicated, and the versions are very similar, gameplay-wise).
