Played on a modified exe that runs the game in 1920x1080. The game's native resolution is 640x480. This walkthrough was played entirely on the HARD difficulty and shows all cinematics, uses and activates all inventions, collects all Red Neutrons (including every particle), gets the highest rank and does not take a death.

Notice that in a normal playthrough certain invention components and activators in specific levels will not spawn depending on how high your score is and what inventions you've previously unlocked. Save file manipulation and Cheat Engine were used to show where they would be in the case if the player's score is low and doesn't have the items to build a particular invention at those points.

I absolutely loved this game when I was a kid, although I was so young that I had no clue what was going on half the time. I still remember it so well even down to the sounds, though.

Dang, this is a walk down memory lane

[TheSlamLord]

I remember playing this game when it came out! I’ve been searching all across the internet to find it again haha Thanks for the nostalgia!

[steveharper]

I miss these type of PC games, they were so much fun back in the day

[augsbourne]

This was one of my favorite games ever growing up! Thanks for bringing a childhood memory back to me.

This game was my childhood. That intro music still randomly pops into mind sometimes.

The virtual reality level was always a fav.

NGL, the Herminator section when Neutron is being chased scared me as a child. Probably because of the music and the design of Herman.

I would quit at that level and then restart the game just to avoid playing that level. Took me a while to beat that level.

Thanks for the trip down memory lane

Just unlocked a core memory of giving my computer aids downloading a demo of this off Nick Arcade when i was like 6

[glitchymangos]

This is literally all that I played before I was allowed access to the internet

[Nasher]

Really wish they made an actual episode of this game. Would of loved to see that.

...did she just call him "Jimmy?"

10 points to anyone who gets that joke. :p

[RowanTheBoat]

omg thank you, i’ve been trying to find gameplay of this, i used to play it all the time as a kid.

[kijetesantakulu]

It's just as glorious as I remember

[dogbogs]

that water level was so creepy to me as a child and it still kind of is

[julianboim]

I never realized this before, but Jimmy from “Jimmy Neutron” is it the same voice actor as um, Nergal Junior from “The Grim Adventures of Billy and Mandy”? Like it sounds that it could be. IDK?

[bizzlier]

The fact that this game isn’t based on a real episode is incredible. If only we would get games from Nickelodeon like this nowadays.

[Kirby]

Would be cool if they remake this game

[AquaDragon-kcfh]

Some of the music in this game is really catchy.
