Everything below comes from the Steam store page’s own feature list and the official patch announcements. No community guesswork.

The headline additions

1. Level Browser: Select Date

The level browser gained the ability to search levels by the date they were published. The store description frames this as a “deep dive into ancient levels of the forgotten past”, which is a real feature rather than marketing: with a library this large and this old, being able to filter by era is the only practical way to find the maps people actually remember.

2. Achievements and stats

The Steam release adds 80 achievements plus global stats. This is the single biggest structural change to the game, because the original had no progression system outside of finishing levels. It also gives the community something new to chase: several achievements are built around long-term counters like total limbs lost or total distance travelled.

3. Account linking

You can link an old Happy Wheels account to your Steam ID, and sign in automatically across devices. For anyone with years of history on the browser version, this is the feature that makes the port feel like a continuation rather than a restart.

4. Controller support

The store page lists partial controller support, naming Xbox controllers. Player reports describe it as the least finished addition, and the developer’s patch notes confirm controller work is ongoing.

5. Offline level downloads

Downloaded levels are stored in a separate list and can be played without a connection. Combined with Steam Deck support, this is the feature that makes the game portable for the first time.

6. No ads

The store description states this directly. If the browser build you were used to was ad-supported, this is a visible difference in ordinary play.

Level browser and account housekeeping

Alongside the headline features, the Steam release reworked the browsing side of the game:

  • A redesigned level browser with sorting and ranking of daily user submissions.
  • Steam Cloud support for your data.
  • Family Sharing support.

What was added after launch

The port has been patched twice since release, and the changes are worth knowing because they affect behaviour:

Patch 1.99.1 (23 September 2026)

  • Replaced the “Publish your first level” achievement with “Complete 10 Editor Playtests”, specifically to slow down the flood of achievement-farming levels.
  • Escape now pauses the game in addition to Tab. F11 toggles fullscreen.
  • Reduced input latency.
  • Fixed a bug where non-standard controllers were detected as input devices.
  • Fixed the Autopilot achievement, a Linux/Wayland startup crash, and a memory leak.

Patch 1.99.2 (26 September 2026)

  • Made the “At What Cost?” achievement more forgiving.
  • Fixed duplicate/ghost windows on Windows 11.
  • Fixed the Steam overlay on Linux.
  • Added a subforum for sharing levels.

Notice what the 1.99.1 achievement change implies: community feedback about achievement-farming levels was acted on within two days. That is a useful signal about how the port is being maintained.

What did not change

  • No new official levels were listed with the release.
  • No graphical overhaul. The store description does not promise one.
  • No multiplayer. The game remains single-player only.
  • No new characters were listed in the store data.
