yeah the maze one was definitely the worst level and i think level P and level J were the ones that i didnt like if i recall correctly but i may be wrong
just double-checked, yea those are the levels i didn't like (though J is the aforementioned maze level)
Level P just kinda didnt offer much in terms of puzzle - the solution is obvious from the start its just kinda wastes time i feel like
the end state is clear on that one yeah, there should probably be an extra step somewhere
J is the maze one yeah, P is the one with 4 boxes that you need to push (some with your tongue) into the doorways
