Broke the server and caused error message overload

I guess this doesn't work for open source games. TPT has almost 100 credited developers but is only 6-7MB.

With Windows 10's EOL approaching, why not try something old. I can confirm the next version of TPT will mark the return of Windows XP support.

MEGA STICKMAN RAGES.

TPT 99.3 is out! Since there were so many bugfixes this month, we decided to do another minor release. Some of the bugs are very old, like gravity wall leaks while undoing, or an infinite pressure bug in the corner. Others were new, like elements being missing in certain older saves.

While I didn't know about the crash before putting out the new update ... turns out we DID fix this crash by accident in 99.2. So all is good in the world.

Windows users using the portable version of 99.1 will get a GAME CRASH when updating to 99.2. It is still safe to run the update. The old instance of TPT will bluescreen, and the new instance will launch. Close the old instance of TPT, and then delete the file Powder_upd.exe that it leaves behind.

Another new minor version has been released - TPT 99.2. It fixes some newly-added bugs from TPT 99.1. That means the fps display is back in line with how it was before (no 0.00 FPS while paused), and some bugs on high refresh rate monitors were fixed.

Go into heat view (6) while it's on and it will color all the air depending on how hot it is. If you have debug hud on (d) it will also show you the exact temperature.

A new minor version of TPT, 99.1, has been released! It fixes some bugs and leftover issues from 99.0, and also some old simulation oddities. Plus, the FPS cap now only applies to the main window, no more rapidly spinning spinners and janky scrolling when you turn off the FPS cap

TPT is open, with the error popup "Sorry, TPT isn't available right now. A law banning The Powder Toy has been enacted in the U.S. Unfortunately, that means you can't use TPT for now."

Oh no, it wasn't just TikTok that was affected!

Happy New Year! In 2024, we added features we talked about and put off since 2014. Next year, my resolution is to do the things I've put off since 2015

A beta for 99.0 has been released! This version adds better search in the save browser, and boosts fps in Fire/Fancy displays by putting rendering into another thread. There's also now in-game credits, a new tools api for creating Lua tools, and various simulation / crash fixes. Download: tpt.io

I see nothing wrong here. That's totally the current logo.
