Note the "What is Replicube?" and "Introductory Puzzles" button on the bottom, which might be easy to miss.

Had hours of fun playing this with my son (steam version). Great work.

Hard to use on a mobile with the keyboard popping over the text editor, but looks like lots of fun. Wish there was a mobile app version.

Man, that's a fantastic way of making me interested in the game. I'd heard of it before, but up until seeing this I figured I'd have to spend money and hop onto my PC (where I play games, as opposed to my work laptop) to check it out.

Now, 15 minutes after clicking the link, I've tried the game out, had a fun time, and ... just might have to buy it.

I'm impressed that this sort of thing was possible with Godot too. Very cool.

OK this is really cool. I'll pick it up on Steam.

Very fun! Not sure if it's a me issue, but the music kept getting static-y in the browser version for me. Maybe something to look into.
yardshop•2h ago
Same for me, when the code is not correct, the music is much slower and very crackly. Once the code gives the correct solution, the music speeds up and the crackles go away.

Also agreed, very fun!

It's an issue with Godot on the web unfortunately, when you're dropping frames the audio starts clipping and crackling. Judging by the other comment, the lua integration must be doing some heavy work.

I think today's answer is actually incorrect. Or at least the reference animation has a hitch where it shows all red for frames 12 and 13. if it shows 2 purples for frame 13 then the animation is smoother and actually the math is much simpler.

Nice!

On the leaderboard I'd like to see code size vs cycles in a 2D plot with the Pareto front highlighted.
