I just got thru it all, (cause I had to do stuff before I could continue), while the idea is very interesting and could lead to many interesting puzzles, relying on pushing of the boxes is, not ideal. It's very easy to push a box into a position you don't want it to, luckily i found a bug where if you stand on the edge of a box it let's me move the box from above so it didn't get stuck as much, but it was still ok, could've designed the puzzles a little better so there wasn't as many issues. Also it would've been a bit nicer if i could read the entity numbers from farther away, had to redo the last puzzle alot cause of that.
