- A new location preview (mentioned in "Votes and tunes at the beach")

- Free in-game goodies
Community Observations and Player Reports
The following items come from community discussion and Steam Community posts. They are not yet confirmed as official patch notes:
- Possible memory issues at launch: Some players on the Steam Community hub reported the 1.0 update "might have some" memory-related issues at launch. This aligns with the developer's emphasis on memory improvements, suggesting the team was addressing known problems.
- Multiplayer stability: Community reports are mixed on how stable the new multiplayer mode is on day one, with some players noting occasional desync in larger parks.

How the 1.0 Update Affects Your Gameplay
Multiplayer Changes Your Park Strategy
The biggest shift in 1.0 is the addition of multiplayer. If you've been playing solo through Early Access, you can now:
- Build and manage a park with friends
- Share the workload of staff management and slide construction
- Experience the ragdoll physics chaos with other players present
For solo players, the performance improvements are the more impactful change. The memory use optimization should mean fewer crashes when your park grows large, which was a common Early Access pain point.
Price Change at 1.0
The game's price increased at full release. If you're coming back to the game after a break, this doesn't affect you—you own the game already. New players joining for multiplayer will pay the full release price.
What Didn't Change
The core loop remains the same: build custom water slides, manage staff, and keep your guests happy. The 1.0 update is a polish and feature-complete release, not a redesign. If you enjoyed the Early Access gameplay, that core experience is intact.
