Thank you! Yes, the level 26 (last) is possible, but quite difficult. (tunnel isn’t necessary, if you didn’t pick that up)
(now level 29 in v1.3)
Still frustrated by level 29. I can get into the position for the hint but by the time I do I've pushed the apple away, so presumably that's no longer a helpful position. perhaps the hint needs a red dot to show the position relative to the apple?
Edit:
Finally solved it but it had zero resemblence to the hint.
