Thank you so much for your thorough feedback - it was fair and I admire it a lot! <3 Thank you for pointing out design mistakes! I did hide secrets only after one specific wall tile and it is used only for this purpose, but it wasn't probably distinguishable enough :D There was a bug with switch you encountered in the last level and yeah, that jump you made from a hidden wall was intended and only way up - so I agree it's another level design mistakes. And yeah, boxes stacking is also a bug I tried to solve :D Thank you for reviewing the puzzles design - they are really simple and straight-forward, I agree. I am learning to make more fun puzzles, yet for this jam I barely made all the mechanics and used them in few simple levels :D
