These casual 3D type games really do deserve more attention. They always allow you to just zone out and use a bit of spacial thinking. In this case it's another title that happily does this and nothing more.
Overall I found it easy enough to get to grips with but includes a couple of tricky puzzles. If I had anything negative to say it's sometimes you have to be exactly within the bounds, sometimes you don't. I'm genuinely unsure if there's a mechanic that a high percentage of the item cannot be covered but a small percentage is OK. This seemed to be really sporadic for me. Generally I'd never have the item covered, but sometimes it accepted it anyway. Not enough that you feel like you're being cheated. It is enough though that sometimes you'll chase a solution only to realise in this case it doesn't work.
