The stone pillar will lean by itself for me. As the @cimarronline said

@Lang Tao Jin - I switched to my tablet and the column falls just fine. I'm not sure why it doesn't fall on my Android phone, but I tried several times.

Other than that it was an interesting level with some ideas I hadn't seen before.

Sorry my friend I can't finish this level as the instabilities make me frustrated. Didn't know what happened at the start but it just happened. Then stucked at the wedge which almost everyone is stucked. When this works, the budgeable won't fall. Already restarted several times but all things won't go smoothly. I had enough. Sorry.

@mastersifu Never mind

As I had problems with the mech & in my opinion that trick is not intuitive I can't give you 5 stars... but when I realized (with @cimarronline hint) what to do was fun... nice design too... Thanks for sharing @Lang Tao Jin

Unfortunately the budgeable did not move for me

Spoiler: VS (v1.6.0)

Thanks so much @RZK for the VS... looks like an absolutely marvellous level but unfortunately for me the budgeable will not "budge" LOL
