All Stars — Level Combos

A star is a collection element that exists three by three in each chapter. You don't need it to have an ending,

Required for progression after clearing

Star	Level	Notes	Combo (spoiler)
1st Star	1-2	The star is blocked by the wall and cannot be taken as it is. Use the level addition used in 1-X to go to another level to get it. If you use the preview of "Chapter Map" in the menu, it is easy to find candidates.	Combo spoiler 1-2 + 1-7
Second Star	1-6	You'll need more keys to claim the stars. Therefore, a level with a surplus fork is a candidate for addition.	Combo spoiler 1-6 + 1-20
Third Star	1-10	Stars exist beyond the pink switch block, but there are no switches in 1-14. Therefore, the level at which the pink switch is present is a candidate for addition.	Combo spoiler 1-10 + 1-24
4th Star	2-16	2-16 You can acquire a star by itself. Because the star-struck entrance is in the middle of the ice sheet, you need to use the box to hold the theta in front of the entrance. Use the technique used in 2-18 to stop the box on the ice.
5th Star	2-0	The stars are beyond the ice sheet on the field and are blocked by thorns. Use the box on the ice sheet. Acquisition is based on clearing 2-X.
6th Star	2-Y	Unlike the first touch, you will not be able to enter 2-Y, so you will need to enter by another means. Use the direct product used in the 2-X Cheats.	Combo spoiler 2-Y * anything
Seventh Star	3-21	There are thorns in the path to the stars, and ghosting cannot be avoided. Look for a combination that you can unlock because you can't get stars without remaining ghosted. Taking advantage of the direct product of levels, the nature of the world line sharing the goal.	Combo spoiler 3-3*3-21
Eighth Star	3-31	The stars are surrounded by walls, and neither additive nor direct. You'll find the techniques you need in Chapter 4, using the level overlay you learned in 3-Y.	Combo spoiler 3-31^3-X
Ninth Star	3-0	Just clear 3-W to get it.
10th Star	4-7	The stars are buried in the pillars, so they can be picked up through the walls, using superposition to combine the levels. Use boxes and prisms to create terrain to fill in the gaps between walls and stars.	Combo spoiler 4-7^4-X
11th Star	4-17	Extremely hard. You must bring two keys over the wall from outside 4-17, and you also need Theta inside the wall. A two-level combo cannot meet the conditions, so use a three-level combo. Deploy 4-K wall plus box overlay, entering the 4-K wall, swaps from 4-M, and similar tricks to cross the wall.	Combo spoiler 4-22+(4-17^4-Y)
12th Star	4-0	It is surrounded by thorns under 4-Y. Use the same method as entering 4-Y.
13th Star	5-24	The path to the stars is blocked by a dark box, and this level alone cannot be taken. It takes advantage of the properties of fading with the light of the dark box and sharing the coordinates of the goal with each world line of the direct product. Also, since 5-24 is long horizontally and vertically, it is necessary to adjust the goal position using non-direct products.	Combo spoiler (5-2+[5+X])^5-24
14th Star	5-0	It is blocked by a switch block in the dark zone to the south. Entanglement is required to press the pink switch. You can also use Unghosting to get out of the darkness just beyond the barbed floor. To press the yellow switch, use the entry technique used in Chapter 4.
15th Star	5-P	The star is in front of the goal and must pass through the goal by some means. You may be able to use both the ice sheet and the entangled state to get through the goal, but if you pass the entangled box packing theta through the goal, the unlocking process will take precedence and the goal will be scored. Use the 5-38 technique.
16th Star	6-12	You need to transport the box to the top right switch to get a star. There is not enough space to take advantage of the tangled state, and the S-shaped bends get in the way of pushing the box. So you need to push the boxed theta with two forks in the other box. Use cross-border to secure two forks. (spoiler image)
17th Star	6-16	The star is beyond the goal, and you can't slip through it. Since pressing the white switch is one of the clear conditions, you can disable the goal by using the cross-border and erasing theta on the white switch from all world lines. Proliferation and reverse procedures are used for theta elimination.
18th Star	6-W	Since there is no level of access other than 6-W, we use 6-W and forks to think about the combination. Crossing the border when the adjacent world line that comes out in 6-V is of different size is a hint, and we use this to generate a tangled box.	Combo spoiler 6-W^(6-W+6-W)

You need to transport the box to the top right switch to get a star. There is not enough space to take advantage of the tangled state, and the S-shaped bends get in the way of pushing the box. So you need to push the boxed Theta with two forks in the other box. Use cross-border to secure two forks. (spoiler image)
