What does the arrow on the yellow cross mean?

It marks the real vertical slide direction for the upper-left five-capacity cross.

When should I move the orange plus?

Wait until the upper bars and the red/white center pieces have opened the lower return corridor.

Catdom 2: No Timer level guide

expert 9 colors

Catdom 2: No Timer Level 29 is the recorded 'CRAZY LEVEL' run, with a vertically constrained yellow cross and a crowded lower orange-plus route.

If the player asks you to sign in, open the video on YouTube instead.

Slide the upper-left yellow cross vertically into the yellow cat group.
Clear the upper purple and white horizontal boxes through their matching lanes.
Use the red vertical box and blue/red 1x1 boxes after the center junction opens.
Route the green vertical box and cyan horizontal box without closing the lower return lane.
Slide the orange plus through the center/lower corridor into the orange cat group.
Finish the lower-right magenta L and the purple/orange feed cats.

Colors in this level:

Yellow, Purple, White, Red, Green, Cyan, Orange, Magenta, Blue

Ignoring the yellow cross’s vertical movement cue and trying to force a sideways route.
Sending the orange plus upward before the white and red pieces have left the central junction.

Respect the yellow cross’s vertical-only cue before opening the upper lanes.
Do not move the orange plus upward until the white and red center pieces have cleared.

Board notes 5 details

Layout: The tall frame opens under a CRAZY LEVEL banner with yellow cross capacity 5 at upper left, purple horizontal capacity 3 at upper right, white horizontal capacity 2 in the upper middle, red vertical capacity 2 on the right, green vertical capacity 2 on the left, cyan horizontal capacity 2 at bottom left, orange plus capacity 4 in the lower middle, magenta L capacity 3 at lower right, and blue/red 1x1 boxes at capacity 1.
Goal: Clear the yellow, purple, white, red, green, cyan, orange, magenta, blue, and red cat groups while keeping the center and lower return lanes open.
Opening: Follow the yellow cross’s vertical arrow first, then clear the purple and white upper bars before sending the orange plus through the center.
Danger Zone: The yellow cross blocks the upper-left route and the orange plus occupies the central lower junction. Green and cyan share the left/bottom return lanes with the final magenta L.
Mechanics: The video labels the board CRAZY LEVEL and shows a vertical movement cue on the five-capacity yellow cross; short 1x1 blockers sit among the larger pieces.
