How the game is structured
Summary
Each room contains either a platforming challenge, a puzzle, or some mix of the two. You move through them in order, and the difficulty varies a lot from room to room. Up to 15 players can be in a room at the same time, so you are never forced to go it alone.
- Rooms 120 in total, ranging from straightforward to genuinely tricky
- Multiplayer up to 15 players share a room at once
- Milestone badges awarded at every ten rooms, from 10 all the way to 120
- Collectibles hidden items scattered through the rooms, separate from the clear condition
- Full completion clearing all 120 rooms and finding every collectible
Getting through a stuck room
Step
The developer has already adjusted some rooms to be less frustrating, but plenty of them still hit hard.
- Watch moving parts study any mechanism in motion before you try it
- Check every edge look along the walls, floor, and ceiling for paths or platforms that blend into the background
- Rotate your camera spin it all the way around to kill blind spots before you decide a route does not exist
The nine collectibles and how to find them
Tips
Collectibles are not always placed behind the clear condition, so you can pick many of them up while you are still exploring a room rather than after you finish it. The full set is: Rat, PS1 Rat, Louie, Cat, Puppy, Rubber Duck, Taco, Tix, and Bunny. Rat, PS1 Rat, and Louie are three separate items even though all three are rats.
- Tix is themed after a currency that existed in Roblox years ago
- Every collectible you grab immediately unlocks its corresponding badge, so you can track which ones you still need
