Your submission is really good 😀
I love the robot animation, it's really add to the immersion.
I think with some music and graphic polish it could really be a good game !
Maybe consider changing platform using the mouse wheel, I think it could be more intuitive.
And it could be a good idea to limit the number of platform the player could create to kinda limit the player and make more interesting puzzles.
Feel free to check this video about making a puzzle games, it greatly helps me :
Congrats for your submission !
