I coudnlt adjust to the ZQSD controls, it is better to go with what most people are accustom to (AWSD), I had to use my keyboard arrows for movement. I still didn't figure the game out. First, I tried to carry yellow box to yellow platform then other colors but they'll kept disappearing once I reach platform area.

It's part of the gameplay for the boxes to reset, watch the clock, and see why it happens.
I wrote the solution in the walkthrough uploaded with the .zip file.
And I pologize for the ZQSD controls, my keyboard is AZERTY, the "default" for me is that, you can always change them in the control Input for the .zip file. I explained everything in the description.
