[Environmental/Trailer] Dream

The eye isn't necessary to get to the end, with double jump and climb you can easily get up there.

You can reach the little island in x1002y1000 without any jump power-ups, but you can't jump back. If the player used the save point on the screen, that means she's stuck and can't leave without editing or deleting her save file. To fix this you can either move the island farther away so that Juni requires jump power-ups to cross, or remove the save point.

Also, I found the jump past the spikey thing on screen x1001y1001 a bit trickier than you may have intended. I'm not sure how you would change it to be easier, though. Get rid of the water maybe?

Alternatively, it can be finished without double jump and hologram.

Using the double jump powerup, it is easy to get to the ledge to the right of the waterfall in x999y1000, and from there you can climb up into a void above.
