The UI never changed so you had to read objectives to use the trash cans and you couldn't beat the game at the end. It seems like a fun idea to have different objectives, and I think it would be a lot better with these issues ironed out. 

ui close button didn't work, so i didn't know the objectives. i had to read the objectives on the page itself in order to know what to do. color coded trash cans were cool, but the game felt too easy as all the trash was out in the open. i also didn't know how to finish the game as nothing happened after getting all the trees into the trash cans and i didn't see a gate. other than that the game worked as intended and the water section was unique.
