I like the idea I can see the potential as a puzzle game. The truth is I almost finished but couldn't. The only thing I need was to throw the green in the gold block on the left but I couldn't do it. I try to jump in but it was to hard or impossible; Then I tried to throw the tops in but wasted all of them... and didn't want to restart and give up.
But I give you the credit in the ideas. I really like the interaction with the floor and that if you throw more than one it speed up the process, very clever. Good work!
