This one is well-presented and ambitious! Cute robot character as well. Good job!
Unfortunately I got stuck on the last puzzle. I thought I had put the tiles in the right order, but whenever I pressed the green button, the tiles shuffled and nothing seemed to happen. It's not clear whether that's what happens because you got the wrong answer, so maybe a "wrong answer" sound effect or icon would help.
It's also easy to miss that you have to click the boxes at the beginning to get the supplies (and that dragging doesn't work) -- maybe starting the player with the boxes already equipped would help, so that they can still explore and progress even if they miss that detail.
The music provided some nice atmosphere, and the way you worked in Hopper was clever!
Hope this helps, and good luck to you in expanding this game. Keep up the good work :)
