I'll give it a thumbs up for originality, but the game is far from perfect. In fact, if it wasn't released years ago, I'd think this game was in early access...
Let's get the good parts out of the way first: it's relaxing, plays reasonably well and has great music. And (as said) is pretty original, which means a lot. It has that typical "one more" sort of thing going on.
The bad part about it is that it makes mistakes that could've been (or even should have been) avoided. The main part: the intro. Yes, I get that it's going for a minimalistic approach. But a simple meter that displays which percentage you've 'covered' isn't too much to ask for, right? Or a visual feedback that you've completed the level.
Even more bothersome is that you have to actually exit the level to see which percentage you actually covered. Or whether you did reasonable, okay or great (not unimportant, as you need to know that for unlockable future things). There's no tutorial either. On one hand, it's not like this game is hard to wrap your head around, but nothing at all is just not enough.
And I'd love it if there were some options on the screen. It's like the only keyboard button to be used is 'escape' (which you'll need to press once you finished a level if you want to actually do anything but admire your wrapped present). I only accidentally stumbled upon the 'restart' option, and I think I'd rather have a rewind and forward button with it...though that may have been too hard to implement. Same for my wish to temporaly turn the object to glass and make anything but 20 cm of rope invisible...I'm sometimes just binding in the blind.
One thing that really shouldn't be that hard is an option to zoom in and out. For the same reasons already mentioned.
EDIT: just noticed that there's some sort of bug...there actually IS a percentage meter, as well as an indication of length. It's just not displayed on my monitor by default for some reason (I get it by alt-tabbing out of the game and then back in again...which for some reasons causes me not to be able to start a level :-\ ). Rather than deleting the above, I'll mention it. Perhaps my 1920x1080 resolution is to blame? :-\
Wow...seems like my last paragraph is quite a lot longer than my previous one. Don't let that fool you, though. I gave it a thumbs up for a reason: the game is certainly fun to play. And despite the mentioned quirks, you actually feel like you're in control of what you're doing. Which is something that isn't that common with 3D puzzlers...
