1. Don't save until after collecting air jump! Go to the air jump orb. Jump above it, press R to kill, and you will fall into the orb while the kill animation plays. Due to the fact that the game's progress is only reset when the animation starts, not after respawning, anything you touch while falling will be kept. Proceed to the left and save in the area to the left of the end bed.

TIMING NOTE: Up until the first save point, you can reset quickly by pressing R. Since the kill animation takes the same amount of time as the intro animation and you spawn at the same place as before, a run timed from pressing S at the start and from pressing R in this way are equivalent.

2. Similar to the step above, head to the dash orb, jump above it, press R to kill, and you should respawn with both air jump and dash. Save at the same area again and go to the heaven/puzzle area.

a. Move all 3 tiles in the first puzzle room to the left side of the previous room. You can get tiles to stop midair by leaving the area and re-entering. Note that you will have to move some tiles up in the previous room before you move them left, otherwise you will not be able to move them up later. b. When all tiles are on the left side, hit the 2 rightmost tiles up, allowing them to travel off-screen. Then, hit the leftmost tile up and dash into the room on the left. This should cause the tile to freeze somewhere between 30-50% of the way down from the top of the room. The aim here is to make a staircase with the 3 tiles. c. Hit one of the upper tiles from below; this can be tricky as they are off-screen. Do the same with the last tile, but jump before falling back into the bottom room. Jumping delays your fall just enough to move the last tile even higher than the second. You can also try to save some time by landing back onto the first tile instead of the ground. It may be easier to perform this by moving the highest tile up first, due to the extra landing time. d. You should now be able to use the tiles like platforms and move into the upper walkway above and to the right, then proceed to the last room with the square. When you are above the square, press R to kill, and you should respawn in the main area with the first square collected.

4. Save to the right of the end bed before continuing to spike square/lava square. You can collect these 2 squares in either order, but after pressing R and collecting one, you need to save again so you can keep it when you death warp for the last square.

5. You should be back at the save point now with all 3 squares collected. If you don't have them all, it means that you either missed a save step or ended up collecting something before pressing R, not after.

6. Otherwise, proceed to the central bed to finish!

If you have any questions, let me know! Step 3 is probably too long/unclear ^^;
