Fun game! I like the idea of preparing my escape! The only down is that I ended up dying a lot and had to place all the props back, an option to copy the prop from last try would be great!
That's a very good idea ^^
Maybe copying the old sollution makes the "thinking about a better sollution" process less well.. existing, but definitly something like this!
Or like someone pointed it out, respawning closer to the object to steal or something like this can make death less punishing
