Hello Replicubers! The first post-release patch is now live on Steam. This update mostly addresses bugs, but also has some new features. Here's a short recap of the changes: • Added autocomplete to the code editor! It only knows about Lua keywords and built-in functions right now, autocompete for user variables or defined functions will come in a future update. • Replipaint is now using multiple threads for a performance improvement • Several improvements to how the game communicates with cubenet • Fixed a few exploits with the token counting (code size) system • when viewing a leaderboard, the game will now jump to your score first • improved documentation formatting I will be sharing my roadmap soon with my plan for future updates and improvements to the game as well, both in-game on cubenet, and here on Steam in the discussion forums. Happy cubing!

I have fun playing this game with my friends. We individually come up with ideas for each level--solve it--then reconvene and try to work together with our different solutions to optimize the problem. It's very enjoyable, would recommend.

Brilliant idea for a game, and very fun to play. I'm inexperienced as a shader programmer though. While I can largely brute-force my way through puzzles, it's unsatisfying knowing that I'm not solving them "the right way." The in-game hints feel a little too abstract for me to learn a lesson from them. For example, on the one with the cute dog, it gives a hint about using max() but I honestly can't figure out how to...

I friggin love this game, What's great: * cute fantasy desktop and social sites * leaderboards * code golfing and optimization * awesome animations * great way to learn how to program What I'd personally love to see: * I would love at least a few more music tracks * PLEASE allow larger voxel models! 16x16 seems too small of a limit, especially for custom creations. If performance is the limiter, use multithreading,...
