Interesting concept !
I mean we thought about the 1D concept but didn't know how to make it playable.
You managed to did it. So a big congrats for that !
I quite did not get what I was doing in some levels but I get into it for sure.
Maybe add a little tutorial based on "how we can detect walls ahead and avoid them" and little tips that will help the player progress ?
Good submission anyway :)
