Cute game!
There is an issue with your fonts, though... I have a feeling that you might be importing your font via a 3rd party? Might I suggest that you use a font you're legally allowed to embed into your project instead? (Players who are security concious will see block text instead. For reference, see attached image.)
Edit: I previously made a bold claim a little too hastily.
Oh wow that's interesting, I've never seen that before.
The fonts are available as free to use online, are embedded in the project and were originally sourced from dafont.com. The links can be found on the game page.
The levels have gotten a bit tricky now, so I'm sure you'll only need a hint instead of a solution here.
I'll assume you've already cleared one of the three gates on the right. As soon as you move that box to weigh down a button, there's no real way (nor any need) to move it again; so you must choose which makes most sense. Both character's arms are long enough to do what you need. At least that bottom character won't be needing to move that box.
The hard part is knowing that all three buttons need to be weighted down somehow. You've done the first and can work out the second, but how will you get the third?
