In the first moment I didnt understood what to do until I read the instructions on your game page - my suggestion is to put some hints how to play somewhere in the game because the mechanics are not selfexplaining (at least for me). 

Not sure what to think about the mechanics, but it felt very unintuitive and annoying to me to point and click on an object with the mouse, to which i just moved the player via keyboard. I think a key for pickup/drop would suffice. 

The idea with the time machine is great and has potential for fancys puzzles in my eyes! 
Maybe a little suggestion here: when using the time machine maybe give the player a clue that this is time travelling (some kind of flying particles, color change or sth. else). On my first play i thought its a kind of sink. 

Last but not least I absolutely love the visual presentation. This is the outstanding part of the game.

I think if you keep tweaking the player controls a bit this would be a very nice and interesting game!

The game mechanic of putting the items in the correct spot is pretty unintuitive, and the icons are hard to spot. The grappling hook is also a bit annoying to use. I like the art though, the player doesn't really fit but i like what's been done with the parallax in the background especially.

Really good graphics, took me a while to understand how to play it but the linked caverns were a cool idea, sometimes it was a bit wonky trying to pick things up!
