I played this game for dozens of hours with my dad growing up and seeing and playing with these animations is one of those times when nostalgia is so overwhelming and unexpected that I feel physically dizzy. If the animation had the sounds of lemmings dying when they fell from too high[1] I might have been hospitalized. Good work.

That’s pretty sweet.

I did something on my site recently like that where you can click a hexagon and it turns into a robot and starts SLAM mapping the page, navigating around text elements carefully.

Were you initially surprised by how easy it was to get exact block size of individual characters and not just entire dom elements? That’s the part I thought was going to be the most difficult.

I recently put lemmings into some clinic management software I've been working on as a software egg.

I enjoy putting the lemming in the margin on the bottom of the viewport at the left or right side then scrolling down such that the lemming plummets. Then, scrolling up, I can make it bounce up as if it is on a trampoline. Very funny.

Cute :) It has a couple of zoom bugs on mobile, something like

html { overflow-x: clip; touch-action: manipulation; }

should fix them!

I don't know if I'm remembering this correctly but there used to be a site called html5lemmings (or something similar) where you could play a few levels of the game. This was before modern web applications and things were still mostly server side rendered with minimal javascript. The demo was quite impressive. I don't know if it's still there. Couldn't find it with a quick search.

Funny how they keep hopping on a toggling horizontal scrollbar there at the bottom.

this is awesome

This sent me on a lemmings hunt and I found someone porting all of the lemmings games and community levels to Mac - https://github.com/ErikVeland/Lemmings

Took me a moment to realise I could pick them up and place them, on things and in things.

Thank you for bringing this to life.

So cute!

love it. I did build a html-in-canvas version (https://github.com/VorticonCmdr/lemmings) for fun and I love how creative other people get

Love it!

It is unfortunate that the scenery is positioned in such a way that lemmings end up falling by the side all the way to the bottom of the screen.

Perhaps it would look better if you removed the padding from <body> and added more pits to the scenery.

Nothing good comes from vib...

Ok, this is awesome.

I vibe-ported xpenguins[1] to Web[2] recently, can be used as bookmarklet and let run on any website. No original Lemmings in that one however, only the knockoff penguins.

Really fun to play around with! Good job!

Cute, but it would look nicer if the walkers were... you know, actually walking? Ok, might be hard to do with CSS to be fair, I don't know enough about CSS animation to judge that.

EDIT: works in Chrome and Firefox, doesn't work in Edge (on Linux - yeah, I know almost nobody uses that) for some reason...

Thank you for making this. It was really fun and a really pleasant start to my day.

This is fantastic.

mad impressive imo, spawned like 50+ ppl and still running smooth (although must say I have a monster rig).

And I overenjoyed throwing lil marios around

Super funny idea ! But it does not follow the scroll down on Safari

I love that they can also walk on the text headings

A tribute to Psygnosis, just for fun

That kind of misses what made Lemmings fun though.

Without digging and building stairs and parachutes, it is only Lemmings in name, not in spirit. Also, exploding lemmings - this can probably be done via CSS animations.

Awesome. Loved the originals.

Oh, this game brings back memories

Now that's what I'm talking about.
