I like the design of the dual clocks, and I think there is a lot of potential for some interesting level design (some of which you have already displayed in the game!). Bouncing off of walls is another great mechanic.
That being said, I actually found the first 3 levels to be the most interesting, because they required you to really use the clocks efficiently and combine the two clocks to move in such a way that you couldn't do with either one of them alone. Levels 4, 5, 6 were in my opinion too straightforward, and too forgiving (I made a complete wrong turn on level 5 and still had enough clock to finish). I think a lot more could've been done for these levels. Maybe if you combined the idea of level 3 with some jumping platforms that would've been cool.
Something that made the game a bit confusing for me was the controls. I was playing on PC and instead of right-clicking to trigger the blue clock I had to click on the right side of the screen (I'm guessing this game was designed for mobile?) Also being able to trigger the clocks with the arrow keys should've been mentioned in the tutorial somewhere.
As for theme, even though I liked the clocks I don't really think they had much to do with time. In fact they sort of felt like energy bars or a mana ability like in many other games which don't deal with time.
Overall I think this is a very promising idea that deserves to be explored further!
